74245 Octal Bus Transceiver IC – DIP-20 Package

The 74245 octal bus transceiver IC provides bidirectional bus communication in a compact 20-pin DIP package. Its 3-state outputs drive bus lines directly, while PNP inputs reduce DC loading on the bus. Hysteresis at the bus inputs improves noise margins.

For a digital circuit that needs bidirectional bus interfacing, this DIP-20 bus transceiver brings together direct bus-line drive and a typical port-to-port propagation delay of 8 ns.
