description
The SN75163B octal general-purpose interface
bus transceiver is a monolithic, high-speed, low-
NOT RECOMMENDED FOR NEW DESIGN
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 modes. 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.
Taking 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
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 SN75163B is characterized for operation from 0°C to 70°C.
