74ALVCH16374T

Overview

The onsemi 74ALVCH16374T is a low-voltage CMOS logic device containing sixteen non-inverting transparent latches. It operates within a supply voltage range of 1.65V to 3.6V, supporting bus-oriented applications with high-speed performance. The component features 3-state outputs and is housed in a 48-TSSOP package. Key electrical specifications include a maximum propagation delay of 3.6ns at 3.3V with 50pF load, a clock frequency of 250MHz, and static current of 40µA. Output drive capability is rated at -24mA for both high and low states.

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing this component, as availability may vary by region. Confirm that the selected unit matches the required 48-TSSOP form factor and voltage specifications. Check for any recent product change notifications or lifecycle status updates from onsemi to ensure long-term supply stability. Ensure compliance with RoHS and REACH regulations relevant to your manufacturing location.

Selection Notes

Select this component for designs requiring sixteen independent latching channels with tri-state output control. It is suitable for systems operating between 1.65V and 3.6V where low power and high speed are critical. Consider the 48-TSSOP package constraints for PCB layout. Evaluate if the 3.6ns propagation delay meets your timing requirements compared to faster alternatives like the ALVC series.

Part Context

This part belongs to the 74ALVCH series of low-voltage CMOS logic devices. It is functionally similar to other 16-bit latch components but optimized for lower voltage operation. The 'H' suffix typically denotes enhanced features such as higher speed or improved noise immunity compared to standard variants. It serves as a key building block for parallel data transfer architectures.

Replacement Considerations

Public confirmed substitute part numbers include SN74ALVCH16374DGGR from Texas Instruments. Verify pin compatibility and electrical parameters before substitution.
