REJ03D0598–0200

(Previous ADE-205-475)

Rev.2.00

Jan 31, 2006

Description

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. The HD74HC245

transfers true data from one bus to the other. This device does not have schmitt trigger inputs.

Features

• 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)

• Ordering Information
