The SN75ALS165 eight-channel generalpurpose interface bus transceiver is a monolithic, high-speed, advanced low-power Schottky device designed for two-way data communications over single-ended transmission lines. It is designed to meet the requirements of IEEE Standard 488-1978. The transceiver features driver outputsthat can be operated in either the passive-pullup or 3-state mode. If talk enable (TE) is high, these ports have the characteristics of passive-pullup outputs when pullup enable (PE) is low and of 3-state outputs when PE is high. Taking TE low places these ports in the high-impedance state. Taking TE and PE low places both the drivers and receivers in the high-impedance state. The driver outputs are designed to handle loads up to 48 mA of sink current.
An active turn-off feature is incorporated into the bus-terminating resistors so that the device SN75ALS165 exhibits a high impedance to the bus when VCC = 0. When combined with the SN75ALS161 or SN75ALS162 management bus transceiver, the pair provides the complete 16-wire interface for the IEEE 488 bus.
The SN75ALS165 is manufactured in a 20-pin package and is characterized for operation from 0°C to 70°C.
