HD75160A
Octal General Purpose Interface Bus Transceivers
ADE-205-590 (Z)
1st. Edition
Dec. 2000
Description
The HD75160A is an 8 channel general purpose interface bus transceiver designed to meet the
requirements of IEEE standard 488-1978. The transceiver features driver outputs which can handle loads
up to 48 mA of sink current if talk Enable(TE) is high, the ports have the characteristics of open collector
outputs when pull up enable(PE) is low, and of three state outputs when PE is high. Taking TE low places
the ports in the high impedance state. The device exhibits a high impedance to the bus when V
CC
= 0 V
since the bus terminating resistors are built in when combined with the HD75161A mangement bus
transceivers, the pair provides the complete 16 wire interface for the IEEE-488 bus.
