CLVCH16652AIDGGREP

Overview

The CLVCH16652AIDGGREP is a 16-bit bus transceiver and register with 3-state outputs, manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation in 5-V input/output environments with 3.3-V VCC. The device consists of D-type flip-flops and control circuitry for multiplexed transmission of data directly from the bus or internal storage registers. It functions as two 8-bit transceivers or one 16-bit transceiver, housed in a 56-pin TSSOP (DGG) package.

Feature Summary

• Supports partial-power-down mode via Ioff circuitry
• Includes active bus-hold on data inputs to eliminate external pullup/pulldown resistors
• Provides latch-up protection exceeding 250 mA per JESD 17
• Features ESD protection exceeding 2000-V human-body model standards

Applications

• Mixed-mode signal operation in systems combining 5-V and 3.3-V devices
• Bus management requiring real-time transfer or stored data selection
• Applications needing isolation between A and B buses with configurable clocking

Procurement Notes

Verify the specific ordering suffix IDGGREP corresponds to the tape and reel packaging configuration required for your assembly line. Confirm that the enhanced plastic qualification pedigree meets your project's environmental stress test requirements. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability consistent with Texas Instruments' controlled baseline manufacturing standards.

Selection Notes

Select this component when designing systems requiring 16-bit bidirectional data transfer with integrated storage capabilities. It is suitable for applications needing voltage translation between 5-V logic and lower voltage supplies within the 1.65-V to 3.6-V range. Consider its active bus-hold feature if minimizing external passive components is a priority for board space reduction.

Part Context

This part belongs to the SN74LVCH16652A-EP family, which is part of Texas Instruments' Widebus family. The -EP suffix indicates an enhanced plastic variant designed for improved reliability. It shares functional similarities with standard catalog versions but includes specific qualification pedigree testing for extended temperature ranges and harsher operating conditions.

Replacement Considerations

The SN74LVCH16652A is the standard catalog equivalent. Verify pinout compatibility and electrical specifications before substitution. Note that the -EP designation implies specific manufacturing controls not present in the standard catalog version.
