SDLS146B – OCTOBER 1976 – REVISED SEPTEMBER 2016 SNx4LS245 Octal Bus Transceivers With 3-State Outputs
1 Features 3 Description These octal bus transceivers are designed for
asynchronous two-way communication between data
buses. The control-function implementation minimizes
external timing requirements. 1 3-State Outputs Drive Bus Lines Directly
PNP Inputs Reduce DC Loading on Bus Lines
Hysteresis at Bus Inputs Improves Noise Margins
Typical Propagation Delay Times Port to Port,
8 ns 2 Applications Building Automation
Electronic Point of Sale
Factory Automation and Control
Test and Measurement The SNx4LS245 devices allow data transmission
from the A bus to the B bus or from the B bus to the
A bus, depending on the logic level at the directioncontrol (DIR) input. The output-enable (OE) input can
disable the device so that the buses are effectively
isolated.
