Product details
Overview
74LVC162373ADL,112 from Nexperia is a 16-bit D-type transparent latch with integrated 30 Ω series termination resistors, dual independent 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 synchronized 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 74LVC162373ADL,112 datasheet, 74LVC162373ADL,112 pinout, 74LVC162373ADL,112 application, or 74LVC162373ADL,112 equivalent, this device supports mixed-voltage translation between 3.3 V logic and 5 V peripherals, enables partial power-down via IOFF, and provides Schmitt-trigger inputs for robust noise immunity on slow-rising control signals.
Technical Context
This latch operates in transparent mode when LE is HIGH-output Q tracks input D with propagation delay as low as 1.0 ns at VCC = 3.3 V-and latches data on the HIGH-to-LOW transition of LE with setup time down to 2.0 ns. Its dual-section architecture allows independent control of two 8-bit channels, enabling selective bus gating without cross-talk.
The integrated 30 Ω series resistors dampen signal reflections on PCB traces up to 100 MHz, while IOFF circuitry disables outputs during power-down to prevent backflow current. Inputs tolerate 5.5 V regardless of VCC, supporting direct interfacing with TTL and legacy 5 V logic without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.2 V to 3.6 V - Enables operation in ultra-low-power IoT nodes and standard 3.3 V embedded systems. |
| Input voltage tolerance | Up to 5.5 V - Allows direct connection to 5 V microcontrollers or sensors without external clamping. |
| Propagation delay (tpd) | 1.0 ns (min) at VCC = 3.3 V - Supports >200 MHz data throughput in transparent mode. |
| Series termination | 30 Ω per I/O - Reduces overshoot/ringing on FR-4 traces up to 10 cm without discrete resistors. |
| IOFF leakage current | ±10 μA max at VCC = 0 V - Prevents damaging back-current during hot-swap or partial power-down sequences. |
| Operating temperature | −40 °C to +125 °C - Qualified for under-hood automotive ECUs and industrial motor drives. |
| ESD protection | HBM >2000 V, CDM >1000 V - Survives handling and board-level ESD events in automated assembly. |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, body width 6.1 mm, lead pitch 0.5 mm, 0.8 mm max height - optimized for high-density PCB layouts with low thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE (pins 1, 24) | Active-low 3-state output enable | Disables corresponding 8-bit output group into high-impedance state without affecting latch contents. |
| 1LE, 2LE (pins 48, 25) | Active-high latch enable | Controls transparency/latching for each 8-bit section; rising edge initiates transparent mode. |
| 1D0–1D7 (pins 47,46,44,43,41,40,38,37) | Data inputs (Section 1) | Accept 5 V tolerant signals; Schmitt-trigger inputs reject noise on slow edges. |
| 2D0–2D7 (pins 36,35,33,32,30,29,27,26) | Data inputs (Section 2) | Electrically isolated from Section 1; enables independent data staging. |
| 1Q0–1Q7 (pins 2,3,5,6,8,9,11,12) | Data outputs (Section 1) | Drive 5 V tolerant loads; 30 Ω series termination reduces trace impedance mismatch. |
| 2Q0–2Q7 (pins 13,14,16,17,19,20,22,23) | Data outputs (Section 2) | Matched timing with Section 1 outputs; skew ≤1.0 ns ensures synchronous bus capture. |
| VCC (pins 7,18,31,42) | Power supply | Four dedicated supply pins minimize switching noise and ground bounce in high-speed operation. |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | Eight ground pins provide low-inductance return paths for all 16 outputs and internal logic. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 8-bit independent control | Separate 1LE/2LE and 1OE/2OE pins allow asymmetric bus management-e.g., latch address while holding data. |
| Integrated 30 Ω series termination | Eliminates need for 16 discrete 30 Ω resistors, reducing BOM count and PCB area in DDR or parallel bus designs. |
| 5 V tolerant I/O at any VCC ≥1.2 V | Enables direct interface with legacy 5 V peripherals (e.g., EEPROMs, DACs) without level-shifter ICs or resistive dividers. |
| IOFF partial power-down | Outputs disable safely when VCC = 0 V, preventing back-current damage during hot-plug or multi-rail sequencing. |
| Schmitt-trigger inputs | Input hysteresis >0.3 V at VCC = 3.3 V rejects >10 ns noise spikes on long control lines in noisy industrial environments. |
Applications
| Industrial PLC Backplane Interface | Automotive Body Control Module |
|---|---|
|
Use Scenario: Isolating microcontroller GPIOs from noisy 24 V I/O expansion cards via optocoupler interfaces. IC Role / Device Role / Timing Role: Transparent latch buffers address/data bus between MCU and isolated peripheral controller, synchronized to clock-enable strobes. Use Value: 30 Ω termination suppresses ringing on 15 cm ribbon-cable traces; 5 V tolerance accepts optocoupler output levels directly. |
Use Scenario: Latching door-lock actuator commands before power delivery in a 12 V automotive body domain controller. IC Role / Device Role / Timing Role: Stores command bits from CAN transceiver until safe power-up sequence completes; outputs drive MOSFET gate drivers. Use Value: IOFF prevents backfeed into powered-down MCU during cold cranking; −40 °C to +125 °C rating matches under-dash environment. |
| Medical Imaging Data Acquisition | Test Equipment Digital Pattern Generator |
|
Use Scenario: Capturing parallel ADC output words (16-bit) from analog front-end before serial conversion to FPGA. IC Role / Device Role / Timing Role: Synchronizes burst-mode ADC samples using LE edge; OE gates data only during valid acquisition windows. Use Value: 1.0 ns tpd ensures sub-ns timing alignment across all 16 bits; matched output skew avoids bit skew errors. |
Use Scenario: Holding digital stimulus patterns for ATE pin electronics while test vectors load into SRAM. IC Role / Device Role / Timing Role: Acts as static pattern register-LE freezes vector, OE enables output to driver stage during test cycle. Use Value: Dual-section control allows interleaved pattern loading and output; 3.6 V VCC supports fast 3.3 V logic families. |
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 VCC range and pinout. | Lacks on-die termination-requires 16 external 30 Ω resistors, increasing layout complexity and cost. | Select when board space permits discrete termination and lower unit cost is prioritized over BOM simplification. |
| 74LVCH162373ADL,112 | Includes bus-hold circuitry on all D inputs; otherwise identical electrical specs and pinout. | Bus hold eliminates need for external pull-ups on unused inputs in floating-bus scenarios (e.g., hot-swap modules). | Select when inputs may be left unconnected during system reconfiguration or field upgrades. |
Compared with SN74LVC16373ADGGR, the 74LVC162373ADL,112 reduces component count and improves signal integrity out-of-box; versus 74LVCH162373ADL,112, it trades bus-hold capability for marginally lower input leakage and identical core latching functionality.

FAQ
Does 74LVC162373ADL,112 support true bidirectional data flow?
No. This is a unidirectional transparent latch: data flows only from D inputs to Q outputs. It lacks internal direction control or bus transceiver logic. For bidirectional applications, separate transmit/receive latches or a dedicated transceiver IC like the 74LVC16245 must be used.
Can 1LE and 2LE be tied together for single 16-bit operation?
Yes. Connecting 1LE and 2LE to the same control signal configures the device as a unified 16-bit latch. Both sections respond identically to the shared enable, maintaining full 16-bit coherence and matching propagation delays across all outputs.
What is the maximum clock frequency supported in transparent mode?
While not a clocked register, the device supports data rates up to 200 MHz in transparent mode, determined by its 1.0 ns minimum propagation delay (tpd) at VCC = 3.3 V and worst-case 7.5 ns maximum delay at −40 °C to +125 °C.
Is the TSSOP48 package RoHS-compliant and lead-free?
Yes. The SOT362-1 (TSSOP48) package for 74LVC162373ADL,112 is fully RoHS-compliant and lead-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and qualified for standard reflow soldering profiles.
