description
The SN75ALS163 octal general-purpose interface bus transceiver is a monolithic, high-speed, advanced
low-power Schottky device. It is designed for two-way data communications over single-ended transmission
lines. The transceiver features driver outputs that can be operated in either the open-collector or 3-state mode.
If talk enable (TE) is high, these outputs have the characteristics of open-collector outputs when pullup enable
(PE) is low and of 3-state outputs when PE is high. T aking TE low places the outputs in the high-impedance state.
The driver outputs are designed to handle loads of up to 48 mA of sink current. Each receiver features pnp
transistor inputs for high input impedance and 400 mV minimum of hysteresis for increased noise immunity.
Output glitches during power up and power down are eliminated by an internal circuit that disables both the bus
and receiver outputs. The outputs do not load the bus when V
CC
= 0.
The SN75ALS163 is characterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to network ground terminal.
2. The package thermal impedance is calculated in accordance with JESD 51.
