Overview

The Toshiba 74HC245D is a high-speed CMOS octal transceiver featuring non-inverting, 3-state outputs, crucial for bidirectional data transfer in digital systems. Its primary function is to facilitate data flow between two buses, offering significant impedance buffering. A key design consideration when implementing this device is the careful management of output enable (OE) and direction (DIR) signals to prevent bus contention, especially in dynamic bus switching scenarios where race conditions can lead to data corruption or excessive current draw. This component is engineered for robust performance within its specified voltage and temperature ranges.

Key Features

Logic Type: Transceiver, Non-Inverting
Number of Elements: 1
Number of Bits per Element: 8
Output Type: 3-State
Supply Voltage: 2V to 6V
Package: 20-SOIC (7.50mm Width)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Parallel bus interfacing in microcontrollers
Data buffering for memory expansion modules
Bidirectional signal routing in FPGAs
Level shifting between digital domains
