HD74BC245A
Octal Bus Transceivers With 3 State Outputs
ADE-205-008A (Z)
Rev. 1
March 1993
Description
The HD74BC245A provides high drivability and operation equal to or better than high speed bipolar
standard logic IC by using Bi-CMOS process. The device features low power dissipation that is about 1/5
of high speed bipolar logic IC, when the frequency is 10 MHz. The device has ten buffers with three state
outputs in a 20 pin package. 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. When G is high, disables both A and B ports by placing then in a high
impedance.
Features
Input/Output are at high impedance state when power supply is off.
Built in input pull up circuit can make input pins be open, when not used.
TTL level input
Wide operating temperature range
Ta = –40 to + 85°C
