SN74ALVCH162831GR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH162831GR is a 1-bit to 4-bit address register/driver with 3-state outputs from the Texas Instruments Widebus family. It operates at supply voltages of 1.65 V to 3.6 V and supports a maximum clock frequency of 150 MHz. The device features active bus-hold circuitry on data inputs, eliminating the need for external pullup or pulldown resistors. Outputs include equivalent 26-Ω series resistors to reduce overshoot and undershoot without requiring external components. It provides ESD protection exceeding 2000 V per the human-body model and latch-up performance exceeding 250 mA per JESD 17.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable as a buffer or edge-triggered D-type flip-flop based on the logic level of the select input
• Integrated active bus-hold circuitry maintains valid logic states on unused or undriven inputs
• Outputs incorporate internal equivalent series resistors to minimize signal overshoot and undershoot

Buffers, Drivers, Receivers, Transceivers Applications

• Driving four separate memory locations from a single address bus
• High-speed digital systems requiring configurable buffering and latching
• Low-voltage logic interfaces operating between 1.65 V and 3.6 V

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'GR' corresponds to the DBB TVSOP package and tape-and-reel configuration. Confirm that the required voltage range aligns with the 1.65 V to 3.6 V specification. Ensure design considerations account for the 26-Ω internal output resistance when calculating load requirements. Check for any recent production notices regarding availability or parameter updates.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single address line must drive multiple destinations simultaneously. The dual output-enable inputs allow independent control over two groups of outputs. The device is suitable for applications requiring both transparent buffering and registered storage modes within a single integrated circuit. Consider the 56-pin TVSOP package constraints for board layout.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ALVCH family, designed for low-voltage CMOS applications. It is part of the Widebus family, which emphasizes high-density packaging and robust output drivers. The device serves as a bridge between standard logic levels and high-speed memory or peripheral interfaces in modern electronic designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consult official documentation for direct pin-compatible substitutes. Verify that alternative parts support the same 1.65 V to 3.6 V operating range and 150 MHz clock frequency. Ensure replacement devices offer comparable ESD protection and latch-up ratings.
