description/ordering information
The SN75ALS160 eight-channel general-purpose interface bus transceivers are monolithic, high-speed,
advanced low-power Schottky (ALS) devices designed for two-way data communications over single-ended
transmission lines. This device is designed to meet the requirements of IEEE Standard 488 - 1978. The
transceivers feature driver outputs that 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. The
driver outputs are designed to handle loads up to 48 mA of sink current.
An active turn-off feature has been incorporated into the bus-terminating resistors so that the device exhibits
a high impedance to the bus when V_CC = 0. When combined with the SN75ALS161 or SN75ALS162 bus
management transceiver, the pair provides the complete 16-wire interface for the IEEE - 488 bus.
The SN75ALS160 is characterized for operation from 0°C to 70°C.
