| HD75161A Octal General Purpose Interface Bus Transceivers ADE-205-591 (Z) 1st. Edition Dec. 2000 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 VCC = 0 V since the bus terminating resistors are built in. If featurs driver outputs which can handle loads up 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.

ATN is a normal transceiver channel that functions additionally as an internal direction control or talk enable for EOI whenever the DC and TE inputs are in the same state. 2. Direction of data transmittion is from the terminal side to the bus side and the direction of data receiving is from the bus side to the terminal side. Data transfer is noninverting in both directions.
