SN74ALVCHR16269GR

Overview

The SN74ALVCHR16269GR is a 12-bit bus exchanger from the Texas Instruments ALVC family, housed in a 56-pin TSSOP package. It operates within a supply voltage range of 1.65 V to 3.6 V and supports an operating temperature range of -40°C to +85°C. The device features true outputs with a current drive capability of 24 mA and low static power consumption of 40 µA. Bus-hold inputs eliminate the need for external pull-up resistors.

Feature Summary

• Configurable as a 12-bit or 24-bit universal bus function
• Provides true output signals for direct data routing
• Integrates bus-hold circuitry on all inputs to prevent floating states

Applications

• High-speed memory subsystems requiring bus interlacing
• Data routing between multiple system buses
• Memory interleaving applications in high-performance computing

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and ensure the component matches the required moisture sensitivity level for your assembly process before finalizing orders.

Selection Notes

Select this component when a widebus configuration is needed for 12-bit or 24-bit data paths. Ensure the design accommodates the 1.65-V to 3.6-V supply range and utilizes the integrated bus-hold feature to simplify input termination requirements compared to standard logic families.

Part Context

This device belongs to the ALVC (Advanced Low-Voltage CMOS) Widebus family, designed for high-performance systems. It complements other bus interface components like the SN74ALVCH16260 by offering specific exchange functionality rather than simple latching or transceiving capabilities within the same low-voltage ecosystem.
