SN74ALVCH16832DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16832DGGR is a 1-to-4 address register/driver with 3-state outputs from the Texas Instruments Widebus family. It operates within a supply voltage range of 1.65 V to 3.6 V and features active bus-hold circuitry on data inputs, eliminating the need for external pullup or pulldown resistors. The device provides latch-up performance exceeding 250 mA per JESD 17 and includes ESD protection that exceeds JESD 22 specifications, including 2000-V human-body model, 200-V machine model, and 1000-V charged-device model ratings.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Configurable as a buffer or register based on the logic level of the select (SEL) input
• Active bus-hold circuitry maintains valid logic states on unused or undriven inputs
• Edge-triggered D-type flip-flop storage triggered by positive clock transitions
• Dual output-enable controls allowing independent management of two groups of seven outputs

Buffers, Drivers, Receivers, Transceivers Applications

• Driving four separate memory locations from a single address bus
• Buffering address lines in low-voltage digital systems
• Registering address data for multi-bank memory architectures

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DGGR corresponds to the TSSOP package and tape-and-reel configuration required for your assembly process. Confirm that the component meets RoHS standards and matches the manufacturer's current production data sheet specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring simultaneous buffering and latching capabilities for address buses. Ensure the design accommodates the dual OE control structure and utilizes the SEL pin to toggle between transparent buffer mode and edge-triggered register mode effectively.
