74LVX16373TTR

Latches Overview

The 74LVX16373TTR is a low voltage CMOS 16-bit D-type latch with 3-state outputs and 5V tolerant inputs. It operates within a supply voltage range of 2V to 3.6V, featuring power down protection on all inputs that accepts 0V to 7V regardless of the supply voltage. The device provides high-speed performance with a maximum propagation delay of 5.4 ns at VCC = 3V. It exhibits low power dissipation with a quiescent supply current of 4 μA (max) at TA=25°C. The TSSOP-48 package supports symmetrical output impedance with |IOH|=|IOL|=4 mA (min) at VCC=3V.

Latches Feature Summary

• Features 5V tolerant inputs allowing direct interfacing between 5V and 3V logic levels without level shifting components.
• Includes power down protection on all inputs, enabling acceptance of input voltages from 0V to 7V independent of the supply voltage state.
• Provides balanced propagation delays where tPLH is approximately equal to tPHL for consistent signal timing.
• Offers improved latch-up immunity and ESD protection circuits providing 2kV immunity against static discharge.

Latches Applications

• Low power battery operated electronic systems
• Low noise 3.3V logic applications
• Interfacing 5V logic devices to 3V logic devices

Latches Procurement Notes

Verify the specific ordering code matches the required tape and reel packaging configuration. Confirm the operating temperature range requirements align with the specified -55°C to +125°C limits. Ensure design compatibility with the TSSOP-48 mechanical dimensions and pinout assignments provided in the datasheet before finalizing procurement specifications.

Latches Selection Notes

Select this component when designing systems requiring 16-bit data latching with 3-state bus control capabilities. It is suitable for applications demanding low power consumption and high-speed operation under low voltage conditions. Consider its 5V tolerance feature if the system involves mixed voltage domains. Verify that the TSSOP-48 package size fits the available PCB real estate constraints.

Latches Part Context

This part belongs to the 74LVX series of low voltage CMOS logic devices manufactured by STMicroelectronics. It maintains pin and function compatibility with the standard 74LS16373 series while offering enhanced performance characteristics such as lower power dissipation and higher speed. The LVX series is designed specifically for modern low voltage digital applications requiring reliable data storage and transfer.

Latches Replacement Considerations

Check for functional equivalents within the 74LVX family or other manufacturers' 16-bit latch offerings. Ensure any replacement maintains the same 3-state output functionality and 5V input tolerance. Verify package compatibility and pinout alignment to avoid redesigning the printed circuit board layout during substitution.
