74VHC245M – FSC

Overview

The onsemi 74VHC245M is an advanced octal transceiver designed for high-speed digital signal buffering and level translation. Its key operational characteristic is its ability to provide non-inverting, 3-state bidirectional data transfer across an 8-bit bus, supporting supply voltages from 2V to 5.5V. A critical design consideration when implementing this device is managing the inherent propagation delay, which, while minimized in the VHC family, can still impact timing-critical applications requiring precise synchronization between multiple bus transactions. This component excels in scenarios demanding robust signal integrity and flexible bus control.
