SN74ALVCH162832GR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH162832GR is a 1-bit to 4-bit address register/driver with 3-state outputs, designed for 1.65-V to 3.6-V VCC operation. It belongs to the Widebus family and features equivalent 26-Ω series resistors in the output ports to eliminate the need for external components. The device includes bus hold on data inputs to remove the requirement for external pullup/pulldown resistors. Latch-up performance exceeds 250 mA per JESD 17, and ESD protection exceeds JESD 22 standards, specifically 2000-V human-body model and 200-V machine model.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated equivalent 26-Ω series resistors in output ports to reduce overshoot and undershoot without external components
• Active bus-hold circuitry on data inputs maintains valid logic states for unused or undriven lines
• Configurable as buffer or register via SEL input; edge-triggered D-type flip-flop stores data on positive CLK transition
• Dual OE inputs control two groups of seven outputs each, managing normal logic states or high-impedance conditions

Buffers, Drivers, Receivers, Transceivers Applications

• Driving single address buses to four separate memory locations
• Buffer applications where outputs follow inputs controlled by OE inputs
• Register applications requiring storage of address data on clock transitions

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix GR corresponds to the tape and reel packaging configuration. Confirm that the DGG package variant matches the required PCB footprint and pin count specifications. Ensure compatibility with the intended supply voltage range between 1.65 V and 3.6 V. Check for any updates to the datasheet revision date to confirm current manufacturing status and parameter validity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring simultaneous buffering and latching of address signals across multiple memory banks. The integrated series resistance simplifies layout by removing external damping components. Consider the dual OE structure if independent control over different output groups is necessary. Verify that the operating temperature range of -40°C to 85°C meets environmental requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device is part of Texas Instruments' Widebus family, which focuses on high-density bus driving solutions. It serves as a specialized interface component for memory systems where address multiplexing or registration is critical. The combination of driver and register functions in a single package reduces board space compared to using discrete logic gates and flip-flops.
