Nexperia USA Inc. 74LVCH16373ADGVJ

Overview

74LVCH16373ADGVJ from Nexperia is a 16-bit D-type transparent latch with 3-state outputs, dual latch enables (1LE/2LE) and dual output enables (1OE/2OE), operating from 1.2 V to 3.6 V supply, tolerant to 5.5 V inputs/outputs, and featuring bus hold on all data inputs. It serves as a level-translating data latching interface in mixed-voltage memory or bus buffering systems.

For engineers reviewing the 74LVCH16373ADGVJ datasheet, 74LVCH16373ADGVJ pinout, 74LVCH16373ADGVJ application, or 74LVCH16373ADGVJ equivalent, this device is selected for high-density 16-bit data capture in industrial control backplanes, FPGA I/O expansion interfaces, and 3.3 V/5 V mixed-signal system interconnects where IOFF-enabled partial power-down and Schmitt-trigger noise immunity are required.

Technical Context

The device implements two independent 8-bit transparent latch sections, each controlled by dedicated LE and OE signals, enabling selective latching and tri-state control per byte. Its bus hold circuitry eliminates external pull-ups on all 16 data inputs, and Schmitt-trigger inputs tolerate slow-rising signals across its full −40 °C to +125 °C temperature range.

IOFF protection disables outputs during power-down to prevent backflow current, while 5.5 V overvoltage tolerance allows direct interfacing with legacy 5 V logic without level shifters. The TVSOP48 package (SOT480-1) supports fine-pitch PCB routing in space-constrained embedded controllers and communications modules.

FAQ

What is the maximum clock frequency supported by 74LVCH16373ADGVJ?

The 74LVCH16373ADGVJ is not a clocked register but a transparent latch: its speed is defined by propagation delay (tpd), not clock frequency. With tpd ≤ 5.5 ns at VCC = 3.3 V, it supports reliable data capture in systems with ≤100 MHz bus handshaking rates, provided setup/hold times (tsu = 2.0 ns, th = +0.9 ns) are met by the controlling logic.

Can 74LVCH16373ADGVJ be used with a 1.8 V supply?

Yes - the device is fully specified from 1.2 V to 3.6 V. At 1.8 V, VIH is 0.65 × VCC = 1.17 V and VIL is 0.35 × VCC = 0.63 V, ensuring compatibility with 1.8 V logic families. Propagation delay increases to 11.4 ns (typical), and output drive strength decreases proportionally, but remains sufficient for point-to-point routing within typical PCB trace lengths.

Does the bus hold feature affect power consumption?

Bus hold draws ±60 μA to ±75 μA per input at VCC = 3.0 V when holding a logic state, increasing total ICC by up to ~1.2 mA with all 16 inputs active. This is negligible compared to dynamic switching current and is offset by eliminating external pull-up resistors (typically 10 kΩ × 16 = 4.8 mW at 3.3 V), resulting in net power savings in most configurations.

How does IOFF protection function during partial power-down?

When VCC = 0 V, the IOFF circuit disables all outputs regardless of OE/LE states, limiting leakage to ±10 μA maximum even with 5.5 V applied to any I/O pin. This prevents reverse current from powered downstream circuits into the unpowered latch, protecting both the device and adjacent components during hot-swap or staggered power sequencing.
