Nexperia USA Inc. 74LVT16373ADL,118

Overview

74LVT16373ADL,118 from Nexperia is a 3.3 V 16-bit transparent D-type latch with 3-state outputs, designed for high-speed bus interface and data buffering in industrial and telecom systems. It features dual 8-bit latch enable (1LE/2LE) and output enable (1OE/2OE) controls, ±64 mA/–32 mA output drive, and bus-hold inputs eliminating external pull-ups. Operates across –40 °C to +85 °C with 2.7 V to 3.6 V supply.

For engineers reviewing the 74LVT16373ADL,118 datasheet, 74LVT16373ADL,118 pinout, 74LVT16373ADL,118 application, or 74LVT16373ADL,118 equivalent, this device is selected for synchronous data latching in 3.3 V backplane interfaces, memory address/data bus isolation, and hot-swap-capable I/O expansion where low propagation delay (<3.9 ns), overvoltage-tolerant inputs (to 5.5 V), and power-down leakage control are critical.

Technical Context

The 74LVT16373ADL,118 implements two independent 8-bit transparent latch sections, each with dedicated active-HIGH latch enable (1LE/2LE) and active-LOW output enable (1OE/2OE). Its BiCMOS architecture enables TTL-level compatibility while supporting 3.3 V logic domains.

Bus-hold circuitry maintains stable logic states on unused data inputs without external resistors, and IOFF protection ensures minimal leakage during partial power-down. The device supports live insertion/extraction and includes power-up 3-state behavior to prevent bus contention at startup.

FAQ

Does the 74LVT16373ADL,118 support live insertion in powered-backplane systems?

Yes. Its IOFF circuitry ensures near-zero power-off leakage (±100 μA max), and bus-hold inputs maintain defined logic states during insertion. Combined with power-up 3-state behavior, this enables safe hot-plug operation in modular chassis without bus contention or latch-up risk.

Can the 74LVT16373ADL,118 interface directly with 5 V CMOS logic outputs?

Yes. Its inputs tolerate up to 5.5 V regardless of VCC level (2.7–3.6 V), allowing direct connection to 5 V CMOS or TTL outputs without level shifters. This is confirmed by the VI input voltage specification (0–5.5 V) and overvoltage tolerance feature in the datasheet.

What is the maximum clock frequency supported for transparent mode operation?

While not a clocked device, its 1.8 ns typical D→Q propagation delay at 3.3 V supports effective data throughput up to ~270 MHz in transparent mode. The 1.5 ns minimum set-up time and 1.0 ns hold time further enable reliable operation with fast edge-rate signals.

How does the bus-hold function eliminate external pull-up resistors?

Each data input has integrated bus-hold circuitry providing ±75 μA to ±135 μA bias current, actively maintaining the last-valid logic state when the input floats. This replaces discrete 10 kΩ–100 kΩ pull-ups, saving PCB space and reducing BOM count across all 16 inputs.
