Description

The HD75161A is an 8 channel general purpose interface bus transceiver designed to meet the requirements of IEEE

standard 488-1978. The transceiver is to provide the bus management and data transfer signals during operating in a

controller instrumentation system. When combined with the HD75160A octal bus transceiver, the HD75161A provides

the complete 16 wire interface for the IEEE 488 bus. The HD75161A features eight driver receiver pairs connected in a

front to back configureation to form input/output ports at both the bus and terminal sides. The direction of data through

these driver receiver pairs is determined by the DC and TE enable signals. The device exhibits a high impedance to the

bus when V

to 48 mA of sink current. Each receiver features p n p transistor inputs for high input impedance and guaranteed

hysteresis of 400 mV for increased noise immunity.
