Two latches are controlled together by one of two active-HIGH enable inputs (LE12 and LE34). While the enable (LE) input is HIGH, data present at the D input passes straight through to the Q output — the latch is \"transparent.\" When the enable input goes LOW, the last data value present just before the transition is captured and held stable at the output, regardless of further changes on the D input, until the enable goes HIGH again.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eCore Electrical Ratings:\u003c\/h2\u003e\n\u003cdiv dir=\"ltr\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eParameter\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eSymbol\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eRating\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage Range\u003c\/td\u003e\n\u003ctd\u003eVCC\u003c\/td\u003e\n\u003ctd\u003e2.0V to 6.0V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Latches\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003e4 (Quad)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLogic Family\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003eHigh-Speed CMOS (HC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePropagation Delay (typ., CL=15pF, VCC=5V)\u003c\/td\u003e\n\u003ctd\u003etPHL\/tPLH\u003c\/td\u003e\n\u003ctd\u003e~11ns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Capacitance\u003c\/td\u003e\n\u003ctd\u003eCI\u003c\/td\u003e\n\u003ctd\u003e~3.5pF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Type\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003eComplementary (Q and Q̄)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eESD Protection (HBM)\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;2000V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eESD Protection (Machine Model)\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;200V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature Range\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003e-40°C to +125°C (typical for HC series)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003e—\u003c\/td\u003e\n\u003ctd\u003e16-Pin PDIP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch2 dir=\"ltr\"\u003ePin Function Overview:\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003enD (Data Inputs):\u003c\/strong\u003e Data to be latched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLE12 \/ LE34 (Latch Enable):\u003c\/strong\u003e Controls whether latches 1\u0026amp;2 \/ 3\u0026amp;4 are transparent (HIGH) or holding (LOW)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003enQ \/ nQ̄ (Outputs):\u003c\/strong\u003e Complementary latched outputs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVCC \/ GND:\u003c\/strong\u003e Located on the center pins of the package (note: this differs from many standard 74-series ICs where power pins are at the corners — always double-check pinout before wiring)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 dir=\"ltr\"\u003eImportant Usage Notes:\u003c\/h2\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eCMOS input handling:\u003c\/strong\u003e As a CMOS device, unused inputs should never be left floating — tie them to VCC or GND as appropriate, since floating CMOS inputs can cause unpredictable output states, excess power consumption, or latch-up.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter-pin power arrangement:\u003c\/strong\u003e Unlike many standard logic ICs with power at the corner pins, this device has VCC and GND on the center pins — a common wiring mistake when swapping this part into a board designed for a different pin arrangement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage compatibility:\u003c\/strong\u003e The HC-series logic family operates from 2V to 6V and is generally NOT directly TTL-output compatible at the input threshold level without care — if this is being used in a mixed TTL\/CMOS system, verify voltage threshold compatibility (HCT-series is typically used instead for that purpose).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote on part status:\u003c\/strong\u003e This particular device (SN74HC75N in PDIP package) has been marked \"Obsolete\" by some distributors, meaning it may be increasingly difficult to source directly from TI;
