SN74ALVC162834GR

Universal Bus Functions Overview

The SN74ALVC162834GR is an 18-bit universal bus driver with 3-state outputs from the Texas Instruments Widebus family. It operates from 1.65 V to 3.6 V and features a maximum propagation delay of 3.8 ns at 3.3 V. The device provides ±12-mA output drive capability and includes equivalent 26-Ω series resistors within the outputs to reduce overshoot and undershoot without requiring external components. Data flow from A to Y is controlled by the OE input, while LE and CLK inputs manage transparent or latched modes.

Universal Bus Functions Feature Summary

• Supports data latching via dedicated latch-enable (LE) and clock (CLK) inputs for synchronized storage
• Integrates internal series resistance to minimize signal overshoot and undershoot on transmission lines
• Provides high ESD protection exceeding specified human-body, machine, and charged-device model thresholds

Universal Bus Functions Applications

• High-density data buffering in portable electronic devices
• Clock distribution networks requiring precise timing control
• Bus architectures utilizing wide parallel data paths

Universal Bus Functions Procurement Notes

Verify the specific ordering suffix against the manufacturer's current package option addendum to confirm the physical footprint matches the design requirements. Ensure that the selected variant aligns with the required moisture sensitivity level and lead finish specifications for the intended assembly process.

Universal Bus Functions Selection Notes

Select this component when designing systems requiring simultaneous data capture across multiple channels. The integrated latching functionality reduces pin count compared to standard drivers. Confirm that the supply voltage range accommodates the lowest system operating voltage to ensure proper logic threshold compliance.

Universal Bus Functions Part Context

This device belongs to the ALVC logic family, characterized by low voltage operation and high-speed performance. It is part of the Widebus family designed for applications requiring large data word widths. The GR suffix indicates a TSSOP package configuration suitable for surface-mount assembly.

Universal Bus Functions FAQ

How does the device handle data during power-up?

To ensure the outputs remain in a high-impedance state during power-up or power-down, the OE pin should be tied to VCC through a pullup resistor.

What determines the data storage mode?

Data is stored in the latch/flip-flop on the low-to-high transition of the CLK input when the LE input is held high.
