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
H = high level, L = low level, X = irrelevant,
Z = high-impedance state
This is the high-impedance state of a normal 3-state output
modified by the internal resistors to VCC and GND.
488-1978. The transceiver features 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. 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 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.
