7448 BCD To 7 Segment Decoder Driver IC 74LS48 SN74LS48N 74HC48

The 74LS48 feature active-high outputs for driving lamp buffers or common-cathode LEDs. They have full ripple-blanking input/output controls and a lamp test input. Display patterns for BCD input counts above 9 are unique symbols to authenticate input conditions.  Their circuits incorporate automatic leading and/or trailing-edge zero-blanking control (RBI\ and RBO\). Lamp test (LT\) of these types may be performed at any time when the BI\/RBO\ node is at a high level. They contain an overriding blanking input (BI\), which can be used to control the lamp intensity by pulsing or to inhibit the outputs. Inputs and outputs are entirely compatible for use with TTL logic outputs.

Features:

• Internal Pull-Ups Eliminate Need for External Resistors
• Lamp-Test Provision
• Leading/Trailing Zero Suppression
• Lamp Intensity Modulation Capability

Package Includes:

• 1 x 7448 BCD To 7 Segment Decoder Driver IC 74LS48 SN74CH48N 74HC48
