74FCT162543TPVCG4

Buffers, Drivers, Receivers, Transceivers Overview

The CY74FCT162543TPVCG4 is a 16-bit latched transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports TTL input and output logic levels. The device features three-state outputs with a low-level output current of 24 mA and a high-level output current of -24 mA. Propagation delay is specified at 8 ns under standard conditions. It functions as a non-inverting registered transceiver housed in a 48-pin SSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer between external buses and local circuitry via sixteen independent channels.
• Integrates D-type flip-flops to latch input data, isolating the bus from source changes during transmission.
• Features three-state outputs that disconnect from the bus when disabled to prevent signal contention.

Buffers, Drivers, Receivers, Transceivers Applications

• High-density memory module architectures requiring buffered address and data lines.
• Clock distribution networks utilizing registered buffering for signal integrity.
• Control signal routing in industrial automation systems.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status per manufacturer documentation. Confirm the package type matches the required footprint for PCB layout. Ensure the operating temperature range aligns with system environmental constraints. Cross-reference the datasheet revision date to verify current electrical characteristics before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring sixteen-bit wide data paths with built-in storage capabilities. The FCT logic family offers speed suitable for moderate-frequency digital systems. Verify that the 48-SSOP package dimensions fit the available board space. Consider the power consumption profile relative to other logic families if thermal management is critical.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74FCT logic family, designed for Fast CMOS performance with TTL-compatible inputs. The 162543 variant specifically provides latched functionality, distinguishing it from standard non-latched transceivers like the 16245. It serves as a bridge between microprocessors and peripheral devices in complex digital designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The CY74FCT162543T is a functional equivalent without the G4 suffix. Other compatible parts include the PI74FCT16543T and NXP 74ABT16543. Verify pin compatibility and electrical parameters before substituting these alternatives.
