74FCT162245CTPAG8

Overview

The Renesas Electronics Corporation 74FCT162245CTPAG8 is a dual bus transceiver belonging to the 74FCT logic series. It features two independent 8-bit channels, providing a total of 16 bidirectional data paths within a single package. The device operates with non-inverting polarity and utilizes TTL-compatible input and output voltage levels. It is housed in a 48-pin TSSOP surface-mount package. Electrical specifications include a maximum high-level output current of -24mA and a maximum low-level output current of 24mA. The propagation delay is specified at 3.5ns under a 50pF load condition. The component supports a supply voltage range from 4.5V to 5.5V and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture supporting 16-bit bidirectional data transfer
• TTL-compatible input and output logic levels for system integration
• High-drive capability with symmetric 24mA output currents
