SN74ALVCH162827DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH162827DGGR is a 20-bit noninverting buffer/driver with 3-state outputs, part of the Texas Instruments Widebus family. It operates at supply voltages from 1.65 V to 3.6 V and features two independent 10-bit sections. Each section utilizes separate output-enable signals (OE1 and OE2) that must both be low for the corresponding Y outputs to become active; otherwise, the outputs enter a high-impedance state. The device incorporates bus-hold circuitry on data inputs to maintain valid logic states without external pullup or pulldown resistors.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated bus-hold circuitry maintains unused or undriven inputs at a valid logic state, eliminating the need for external pullup or pulldown resistors.
• Output ports include equivalent 26-ohm series resistors designed to reduce signal overshoot and undershoot, removing the requirement for external series resistors.
• Latch-up performance exceeds 250 mA per JESD 17 standards, ensuring robust operation under electrostatic stress conditions.
• ESD protection capabilities exceed specified thresholds for human-body, machine, and charged-device models as defined by JESD 22 standards.

Buffers, Drivers, Receivers, Transceivers Applications

• High-density data buffering in memory architectures
• Clock distribution networks requiring controlled slew rates
• Bus driver applications within portable consumer electronics

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package marking and ordering suffix against the official TI Package Option Addendum to ensure correct physical dimensions and moisture sensitivity levels. Confirm RoHS compliance status and lead finish specifications directly from the manufacturer's current documentation prior to finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring wide voltage compatibility between 1.65 V and 3.6 V. The dual 10-bit architecture allows flexible partitioning of data buses. Ensure control inputs are tied to VCC or GND during power-up to guarantee the high-impedance state and prevent unintended bus contention.

Buffers, Drivers, Receivers, Transceivers FAQ

How do the output-enable inputs function?

For either 10-bit buffer section, the two output-enable inputs (OE1 and OE2) must both be low for the corresponding Y outputs to be active. If either input is high, the outputs enter a high-impedance state.

Is external resistance required for the outputs?

No, the output ports are designed with equivalent 26-ohm series resistors to reduce overshoot and undershoot, so no external resistors are required.
