74ALVCH162373T

Latches Overview

The onsemi 74ALVCH162373T is a low voltage 16-bit transparent latch with bus-hold and 26Ω series resistors in outputs. It operates within a supply voltage range of 1.65V to 3.6V, featuring 3.6V tolerant control inputs and outputs. The device utilizes advanced CMOS technology for high-speed operation while maintaining low power dissipation. Key electrical characteristics include a maximum propagation delay of 9.0 ns at 1.65V-1.95V VCC, 5.0 ns at 2.3V-2.7V VCC, and 3.8 ns at 3.0V-3.6V VCC. Quiescent supply current is typically 40 µA at 3.6V. The component is housed in a 48-Lead Thin Shrink Small Outline Package (TSSOP) with package number MTD48.

Latches Feature Summary

• Integrated active bus-hold circuitry on data inputs eliminates the need for external pull-up or pull-down resistors to maintain valid logic levels on unused or floating inputs.
• Built-in 26Ω series resistors in the output paths reduce line noise, supporting applications such as memory address drivers, clock drivers, and bus transceivers.
• Patented noise and EMI reduction circuitry enhances signal integrity during high-speed switching operations.
• Robust electrostatic discharge protection capabilities conforming to JEDEC standards for latchup immunity.

Latches Applications

• Memory address driver circuits
• Clock distribution networks
• Bus transceiver and transmitter systems

Latches Procurement Notes

Verify the specific ordering suffix when sourcing this component. The datasheet indicates that devices are available in Tape and Reel packaging; specify by appending the suffix letter “X” to the standard ordering code. Confirm package availability and manufacturer documentation details directly with suppliers to ensure compliance with project requirements.

Latches Selection Notes

Select this component for designs requiring byte-controlled 16-bit latching with integrated termination resistors. The inclusion of bus-hold functionality simplifies board layout by removing external resistor requirements. Ensure the operating voltage aligns with the 1.65V to 3.6V range and consider the propagation delay specifications relative to system timing constraints.

Latches Part Context

This part belongs to the ALVCH logic family, designed for low-voltage applications. It functions as a non-inverting latch with three-state outputs. The device consists of two independent octal sections that can operate independently or be combined for full 16-bit operation by shorting control pins.

Latches Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains compatibility with the 48-lead TSSOP package and supports the required 1.65V to 3.6V operating voltage range.
