SN74ALVCH16245DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH16245DL is a 16-bit (dual-octal) noninverting bus transceiver designed for asynchronous communication between two data buses. It operates from a supply voltage of 1.65 V to 3.6 V and features 3-state outputs with ±24-mA drive capability at 3.3 V. The device includes active bus-hold circuitry on data inputs, eliminating the need for external pullup or pulldown resistors. It provides ESD protection exceeding 2000-V Human-Body Model and 200-V Machine Model standards. Latch-up performance exceeds 250 mA per JESD 17. The SSOP-48 package supports an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Active bus-hold circuitry maintains valid logic states on unused or undriven inputs without requiring external resistors.
• Input tolerance up to 5.5 V enables down-voltage translation applications from higher voltage buses.
• High-drive CMOS technology provides balanced output drive suitable for long PCB traces.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DL' corresponds to the SSOP-48 tube packaging configuration. Confirm that the required supply voltage falls within the 1.65 V to 3.6 V operational range. Ensure input signals do not exceed the 5.5 V absolute maximum rating during operation. Check for RoHS compliance status in the latest orderable addendum.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing 16-bit wide buses requiring high drive strength and low voltage operation. The integrated bus-hold feature simplifies design by removing external pull components. Verify compatibility with system voltage levels, as inputs tolerate up to 5.5 V while core logic operates lower. Consider thermal resistance metrics if multiple devices are mounted closely.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the bus-hold circuitry function?

The active bus-hold circuitry holds unused or undriven inputs at a valid logic state, which eliminates the need for external pullup or pulldown resistors.

What is the maximum input voltage tolerance?

The inputs are tolerant up to 5.5 V, allowing the device to be used in down-voltage translation applications even when connected to 5 V buses.
