SN74ALVCH162344DL

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALVCH162344DL is a 1-bit to 4-bit address driver with 3-state outputs, manufactured by Texas Instruments. It operates from a supply voltage range of 1.65 V to 3.6 V and features a maximum propagation delay of 4.4 ns at 3.3 V. The device provides ±12-mA output drive capability and includes equivalent 26-Ω series resistors on the output ports to reduce overshoot and undershoot without requiring external components. It utilizes active bus-hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors. The component is housed in a 56-pin SSOP (DL) package and supports an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type, as the DL suffix indicates the SSOP package. Confirm the manufacturing status is active production rather than preproduction or obsolete. Ensure the procurement channel sources parts directly from authorized distributors to guarantee authenticity and adherence to standard warranty terms provided by Texas Instruments.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a design requires driving multiple memory addresses from a single source within low-voltage environments. The inclusion of internal series resistors simplifies layout by removing the need for discrete components. Verify that the system's power supply remains within the 1.65 V to 3.6 V range to ensure proper operation and meet the specified electrical characteristics for propagation delay and drive current.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments Widebus family of logic ICs. It is designed specifically for applications where efficient memory addressing is required in low-power, high-speed digital circuits. The integration of bus-hold and internal resistance features distinguishes it from standard buffers by reducing external component count and improving signal integrity in dense PCB layouts.
