74FCT162H245ATPACT

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74FCT162H245ATPACT is a 16-bit bus transceiver utilizing FCT CMOS technology. It features two 8-bit transceivers with non-inverting outputs and three-state capability in a 48-pin TSSOP package. The device operates within a supply voltage range of 4.5V to 5.5V, supporting TTL input levels. It provides symmetric drive currents of 24mA for both high and low states. The component functions across an extended commercial temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer between two buses using direction control logic.
• Integrates bus-hold circuitry on inputs to maintain signal stability during idle states.
• Features three-state outputs that isolate the bus when disabled.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify current availability status as this specific part number may be discontinued or subject to end-of-life notices. Confirm package details match the required 48-TSSOP footprint. Ensure compatibility with existing system voltage requirements of 4.5V to 5.5V. Check for alternative equivalents if production continuity is critical.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 16-bit wide data paths with moderate speed and standard CMOS compatibility. It serves as a direct replacement for older ABT series devices where lower power consumption is needed. Consider the TSSOP-48 package constraints for PCB layout. Verify thermal dissipation capabilities within the specified operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments 74FCT family, designed as a high-speed, low-power CMOS replacement for earlier bipolar technologies. The 74FCT162H245 variant specifically offers bus-hold functionality, distinguishing it from standard 74FCT16245 models which lack this feature. It is part of a broader ecosystem of FCT logic components used in digital interfacing.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The CY74FCT162H245T is a documented equivalent part number offering identical electrical characteristics and pinout configuration. Other manufacturers produce compatible parts under the 74FCT162H245 designation, but verification of specific package dimensions and electrical tolerances is required before substitution.
