TECHNICAL DATA

Octal 3-State Noninverting

Bus Transceiver

IN74LS245

These octal bus transceiver are designed for asynchronous two-way

communication between data buses. The control function implementation

minimized external timing requirements.

The device allows data transmission from the A bus to the B bus or

from the B bus to the A bus depending upon the logic level at the

directional control (DIR) input. The enable input(E) can be used to

disable the device so that the buses are effectively isolated.

• Bidirectional Bus Transceiver in a High-Density 20-Pin Package

• 3-state Outputs Dirve Bus Lines Directly

• P-N-P Inputs D-C Loading on Bus Lines

• Hysteresis at Bus Inputs Improve Noise Margins

• Typical Propagation Delay Times; Port to Port ... 8 ns
