Product details
Overview
74LVC162373ADGG,51 from Nexperia is a 16-bit D-type transparent latch with integrated 30 Ω series termination resistors, dual 8-bit latch enable (1LE/2LE) and output enable (1OE/2OE) controls, 5 V tolerant I/O, and operation across 1.2 V to 3.6 V supply. It functions as two independent 8-bit latches or one unified 16-bit latch in high-speed data buffering applications such as memory address/data bus isolation in industrial microcontroller systems.
For engineers reviewing the 74LVC162373ADGG,51 datasheet, 74LVC162373ADGG,51 pinout, 74LVC162373ADGG,51 application, or 74LVC162373ADGG,51 equivalent, this device supports mixed-voltage translation between 3.3 V logic and 5 V peripherals, features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operates reliably from –40 °C to +125 °C in TSSOP48 packaging.
Technical Context
This latch implements true transparent mode: when LE is HIGH, outputs track inputs with propagation delay as low as 1.0 ns (VCC = 3.0–3.6 V); when LE transitions LOW, it captures and holds input state with setup time of 2.0 ns and hold time of +0.9 ns. Dual independent control paths allow concurrent or staggered latching of two 8-bit data groups.
Each I/O channel includes 30 Ω series termination to reduce signal reflections on PCB traces, while 5 V tolerance enables direct interfacing with legacy 5 V TTL/CMOS without level shifters. The IOFF circuit disables outputs during power-down, blocking backflow current when VCC = 0 V and VI/VO = 5.5 V.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit latch control | Separate 1LE/2LE and 1OE/2OE pins enable asynchronous latching and output gating of two data streams |
| Integrated 30 Ω series termination | Eliminates need for 16 discrete 30 Ω resistors on PCB, reducing BOM count and layout area |
| 5 V tolerant I/O with 1.2 V–3.6 V core | Direct interface with both 3.3 V logic and legacy 5 V peripherals without external voltage translation |
| Schmitt-trigger inputs | Improves noise margin on slow-rising signals (e.g., mechanical switches, long traces) with hysteresis ≥0.3 V |
| IOFF partial power-down | Outputs automatically enter high-Z when VCC = 0 V, preventing backfeed current in hot-plug or multi-rail systems |
Applications
| Industrial PLC Backplane Interface | Automotive Body Control Module (BCM) Data Buffering |
|---|---|
|
Use Scenario: Isolating microcontroller GPIO from noisy 24 V I/O expansion cards in programmable logic controllers. IC Role / Device Role / Timing Role: Transparent latch buffers address/data lines between 3.3 V MCU and 5 V peripheral cards, synchronized to system clock edges. Use Value: 30 Ω series termination suppresses reflections on 10+ cm backplane traces; 5 V tolerance avoids level-shifter ICs and reduces board layer count. |
Use Scenario: Holding sensor status bits (door open/closed, seatbelt fastened) during MCU sleep cycles in body control units. IC Role / Device Role / Timing Role: Latch stores critical status before MCU enters deep-sleep; outputs remain valid while core is powered down. Use Value: IOFF protection prevents leakage current from 5 V sensors into unpowered MCU I/O pins, eliminating wake-up false triggers. |
| Test Equipment Digital Pattern Generator | Medical Diagnostic Imaging Data Capture |
|
Use Scenario: Capturing parallel digital waveforms from FPGA-based pattern generators for real-time validation. IC Role / Device Role / Timing Role: 16-bit latch samples synchronous data bus at precise trigger points; dual LE allows interleaved capture windows. Use Value: Propagation delay ≤3.4 ns (typ) and skew ≤1.0 ns ensure sub-ns timing alignment across all 16 bits for jitter-sensitive measurements. |
Use Scenario: Buffering raw pixel data from CMOS image sensors before compression in portable ultrasound devices. IC Role / Device Role / Timing Role: Acts as pipeline register between sensor interface and low-power DSP, decoupling bursty sensor output from steady processing rate. Use Value: 1.2 V minimum VCC enables integration into battery-powered subsystems; 125 °C rating supports sealed enclosure thermal profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transparent latch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16373ADGGR | No integrated 30 Ω termination; requires external series resistors; identical pinout and logic function | Lacks built-in termination - increases BOM cost and layout complexity for high-speed trace routing | Select when termination is already implemented externally or when lower quiescent current (<1 μA) is prioritized over layout simplification |
| 74LVCH162373ADGG | Includes bus-hold circuitry on all data inputs; otherwise identical electrical specs and pinout | Bus-hold eliminates need for external pull-ups on unused inputs in floating-bus scenarios | Choose when system has unterminated or intermittently driven data buses where input state retention is critical |
Compared with SN74LVC16373ADGGR, the 74LVC162373ADGG,51 reduces PCB footprint and signal integrity risk via integrated termination; versus 74LVCH162373ADGG, it trades bus-hold functionality for slightly lower input capacitance (5.0 pF vs 10–15 pF), benefiting higher-frequency edge rates.

FAQ
What is the maximum clock frequency supported by the 74LVC162373ADGG,51 in transparent mode?
The device does not operate on a clock signal but functions in transparent mode when latch enable (LE) is HIGH. With typical propagation delay of 3.0 ns (VCC = 3.3 V), it supports reliable data throughput up to ~160 MHz for synchronous bus applications, limited only by external timing margins and trace length.
Can the 74LVC162373ADGG,51 be used to translate 5 V signals to a 1.8 V microcontroller?
Yes - its 5 V tolerant inputs accept VI up to 5.5 V regardless of VCC (1.2–3.6 V), and outputs swing rail-to-rail within VCC. When powered at 1.8 V, it safely interfaces 5 V sensors to 1.8 V MCUs, provided output load does not exceed ±12 mA per pin and VO remains within 0–1.8 V.
How does the IOFF feature protect the device during power sequencing?
When VCC = 0 V, the IOFF circuit disables all outputs, limiting OFF-state leakage to ±10 μA even if 5.5 V is applied to any I/O pin. This prevents reverse current flow from live 5 V buses into an unpowered system, avoiding damage and unintended logic states during hot-insertion or asymmetric power-up.
Are the 30 Ω series termination resistors internal to each I/O pin?
Yes - each of the 16 I/O pins integrates a matched 30 Ω series resistor between the internal latch output driver and the bond pad. These resistors are monolithically fabricated and calibrated during wafer test, eliminating variation and enabling consistent source termination without external components.
