Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC245 Octal Bus Transceivers (with 3-state outputs).

Datasheet Details

Part number	HD74HC245
Manufacturer	Hitachi Semiconductor (now Renesas)
File Size	58.29 KB
Description	Octal Bus Transceivers (with 3-state outputs)
Datasheet	HD74HC245_HitachiSemiconductor.pdf

Each device has an active low enable input G and a direction control input, DIR.

When DIR is high, data flows from the A inputs to the B outputs.

When DIR is low, data flows from the B inputs to the A outputs.

High Speed Operation: tpd = 8 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table Enable G L L H H : L : X : high level low level irrelevant Direction Control DIR L H X Operation B data to A bus A data to B bus Isolation HD74HC245 Pin Arrangement DIR A1 A2 A3 A4 A5 A6 A7 A8 GND 1 2 3.
