What is 74ALVCH16374DLG4 used for?
The 74ALVCH16374DLG4 is designed for 16-bit address and data bus pipeline registers in microprocessor, FPGA, DSP, and memory interface designs where low-voltage 1.65 V to 3.6 V operation and high-speed clocked latching are required. Its 3-state outputs enable multiple bus drivers to share a common 16-bit bus with contention-free arbitration. The 48-pin SSOP form factor suits high-density PCB layouts on server boards, networking ASICs, and industrial PLCs.

Frequently Asked Questions
What supply voltage range does 74ALVCH16374DLG4 support, and why does that matter for mixed-voltage bus designs?
The 74ALVCH16374DLG4 operates from 1.65 V to 3.6 V, allowing it to serve as a bus pipeline register between a 1.8 V FPGA I/O bank and a 3.3 V memory bus without an additional level-translation device. This voltage range covers the most common logic families in modern embedded systems, simplifying multi-rail PCB designs and reducing component count by 1 IC per bus segment compared with using a dedicated level shifter.
How many bits does the 74ALVCH16374DLG4 register in a single chip, and how does the active-low OE work?
The device registers 16 bits simultaneously on the rising clock edge and holds them in the D flip-flops until the next clock. Asserting the active-low output enable (OE) pin low drives all 16 outputs from the stored state; de-asserting it places all 16 outputs in high-impedance 3-state mode, allowing multiple 74ALVCH16374 devices to share a 16-bit bus with only one driving at any clock cycle as controlled by arbitration logic.
For a 48-pin SSOP layout, what pitch and land pattern dimensions does the 74ALVCH16374DLG4 require?
The 48-pin SSOP (R-PDSO-G48) package uses a 0.635 mm lead pitch across a body approximately 12.5 mm long, requiring 0.4 mm pad width and 0.2 mm spacing on the PCB land pattern. Designers should add a 100 nF decoupling capacitor within 2 mm of each VCC pin and tie all ground pins to a solid plane to keep switching noise below 200 mV during 24 mA output transitions at full 16-bit toggling.
What end-of-life status should procurement consider for 74ALVCH16374DLG4, and what alternatives exist?
The YTEOL is listed as 0, indicating the device is at or past its estimated production end-of-life, so procurement teams should verify current stock availability and confirm last-time-buy dates with Texas Instruments distributors before committing to new designs. Compatible 16-bit 3-state D flip-flop bus drivers in ALVCH or VHC families with 48-pin or dual 8-bit TSSOP packages should be evaluated as drop-in second-source alternatives.
