SN74HC245AN** is a high-speed CMOS octal bus transceiver manufactured by **Texas Instruments (TI)**.

The SN74HC245AN is a high-speed CMOS octal bus transceiver manufactured by Texas Instruments (TI).

Specifications:

  • Logic Type: Octal Bus Transceiver
  • Technology: CMOS
  • Number of Channels: 8
  • Voltage Supply Range: 2V to 6V
  • High-Level Output Current: -6mA
  • Low-Level Output Current: 6mA
  • Propagation Delay: 13ns (typical at 5V)
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: PDIP-20 (Plastic Dual In-Line Package)
  • Direction Control: DIR pin controls data flow (A to B or B to A)
  • Output Enable: OE pin (active low) for tri-state outputs

Descriptions:

The SN74HC245AN is an 8-bit non-inverting bus transceiver with 3-state outputs. It is designed for asynchronous two-way communication between data buses. The direction of data flow is controlled by the DIR (Direction) pin, and the OE (Output Enable) pin disables the outputs when set high.

Features:

  • Wide Operating Voltage Range: 2V to 6V
  • High-Current Outputs: Drive up to 15 LSTTL loads
  • Low Power Consumption: CMOS technology
  • Balanced Propagation Delays
  • 3-State Outputs for Bus-Oriented Applications
  • ESD Protection Exceeds JESD 22 Standards

This device is commonly used in data buffering, bus isolation, and bidirectional data transfer applications.
