74FCT162H245CTPAG

Buffers, Drivers, Receivers, Transceivers Overview

The IDT74FCT162H245CTPAG is a 16-bit bidirectional bus transceiver belonging to the 74FCT logic series. It integrates two independent 8-bit transceivers within a single 48-pin TSSOP package. The device operates with a supply voltage range of 4.5V to 5.5V and supports TTL input and output levels. Key electrical parameters include a maximum propagation delay of 3.5ns at 50pF load, with high-level and low-level output currents rated at -24mA and 24mA respectively. It functions within an extended commercial temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CTPAG' against manufacturer documentation to confirm pinout compatibility and RoHS status. Ensure the sourcing channel provides traceability to IDT or authorized distributors. Confirm that the component matches the 48-lead TSSOP physical dimensions specified in the official datasheet before integration into the design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring symmetric drive strength for both logic high and low states. The balanced ±24mA current capability distinguishes it from higher-drive variants like the 16245. Verify that the 3.5ns propagation delay meets the timing requirements of the target bus interface speed.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the IDT 74FCT family, which serves as a high-speed CMOS replacement for older bipolar technologies.
