SN74ALVCH16903DLR

Overview

The SN74ALVCH16903DLR is a 3.3-V, 12-bit universal bus driver featuring parity checking and dual 3-state outputs. It operates within a supply voltage range of 2.3 V to 3.6 V. The device supports clock frequencies up to 125 MHz. Propagation delays vary from 1.1 ns to 8.6 ns depending on the signal path and operating conditions. It utilizes an EPIC submicron process and includes active bus-hold circuitry.

Feature Summary

• Supports buffer or edge-triggered register modes via MODE input selection
• Checks parity on APAR with YERR output for error indication
• Active bus-hold circuitry eliminates need for external pullup/pulldown resistors
• ESD protection exceeds 2000 V per MIL-STD-883

Applications

• High-speed data bus buffering
• Parity checking in communication systems
• Edge-triggered data storage applications

Procurement Notes

Verify the specific package variant (DL) against the required pinout and thermal characteristics. Confirm that the operating temperature range meets system requirements. Ensure proper termination and control signal routing for OE, CLK, and MODE pins to maintain signal integrity during high-frequency operation.

Selection Notes

Select this component when a 12-bit wide bus interface with integrated parity verification is required. Consider the dual-output configuration for flexible routing. Evaluate the propagation delay specifications against the maximum system clock frequency to ensure timing compliance.

Part Context

This part belongs to the Texas Instruments Widebus family, designed for high-density digital logic applications. It is manufactured using the EPIC submicron CMOS process, which provides enhanced performance and low power consumption compared to standard CMOS technologies.
