74LVT162373DGG,118

Latches Overview

The NXP USA Inc. 74LVT162373DGG,118 is a BiCMOS 3.3 V 16-bit transparent D-type latch with 3-state outputs and integrated 30 Ω termination resistors. It operates within a supply voltage range of 2.7 V to 3.6 V and supports TTL input/output switching levels. The device features bus-hold data inputs, live insertion/extraction capability, and power-up reset functions. It is housed in a TSSOP48 plastic thin shrink small outline package (SOT362-1) and is specified for operation from -40 °C to +85 °C.

Latches Feature Summary

• Integrated 30 Ω series resistance in both HIGH-state and LOW-state outputs eliminates the need for external termination resistors.
• Bus-hold data inputs eliminate the requirement for external pull-up resistors to hold unused inputs.
• Supports live insertion and extraction without causing bus current loading when outputs are tied to a 5 V bus.
• Provides ESD protection exceeding 2000 V (HBM Class 2) and 1000 V (CDM Class C3), along with latch-up protection exceeding 500 mA.

Latches Applications

• Memory address drivers
• Clock drivers
• Bus receivers and transmitters

Latches Procurement Notes

Verify that the ordering suffix ',118' corresponds to the TSSOP48 (SOT362-1) package variant as documented in the Nexperia datasheet. Confirm the manufacturer designation aligns with Nexperia specifications, as NXP Semiconductors and Nexperia share product lineage. Ensure the specific revision level matches design requirements before finalizing procurement orders.

Latches Selection Notes

Select this component for designs requiring 16-bit latching with built-in output impedance control to reduce noise. It is suitable for systems operating at 3.3 V that require interface compatibility with 5 V systems. Consider its BiCMOS technology for high-performance applications needing fast propagation delays and robust ESD tolerance compared to standard CMOS alternatives.
