Product details
Overview
74LVT162374DL,118 from Nexperia is a 3.3 V, 16-bit edge-triggered D-type flip-flop with integrated 30 Ω series output termination resistors and non-inverting 3-state outputs. It functions as two independent 8-bit registers or one unified 16-bit register, clocked on the rising edge of CP inputs, and operates across -40 °C to +85 °C for memory address drivers, clock distribution, and bus transceivers.
For engineers reviewing the 74LVT162374DL,118 datasheet, 74LVT162374DL,118 pinout, 74LVT162374DL,118 application, or 74LVT162374DL,118 equivalent, key selection criteria include its 30 Ω on-die termination (eliminating external resistors), bus-hold inputs (removing need for pull-ups), and dual 8-bit/16-bit configuration flexibility in TSSOP48 packaging.
Technical Context
This BiCMOS device implements two independent 8-bit D-type flip-flop sections, each with dedicated clock (1CP/2CP) and output enable (1OE/2OE) controls. Each section latches data on the rising edge of its respective clock while supporting 3-state output control via active-low OE signals.
It integrates 30 Ω series resistance per output in both HIGH and LOW states, directly reducing transmission line reflections and ringing in high-speed parallel buses. Bus-hold circuitry on all D inputs maintains valid logic states without external biasing, enabling robust operation with floating or unterminated inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - ensures compatibility with 3.3 V systems and tolerance against rail droop |
| Max Clock Frequency | 150 MHz - supports high-speed synchronous bus operation up to 150 million transitions per second |
| Propagation Delay | 1.5–5.3 ns (tPLH/tPHL) - enables precise timing alignment in sub-7 ns critical paths |
| Output Drive | ±12 mA - sufficient to drive 50 Ω transmission lines or TTL-compatible loads directly |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees interoperability with 5 V TTL logic while powered at 3.3 V |
| Bus-Hold Current | ±75 μA typical - actively retains input state without external components, reducing BOM count |
| Termination Resistance | 30 Ω series per output - matches common PCB trace impedances to suppress signal integrity issues |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm pitch - optimized for high-density PCB layouts with thermal and mechanical reliability in industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1D0–1D7, 2D0–2D7 | Data inputs (16 total) | Asynchronous parallel data inputs for two 8-bit sections; feature bus-hold for floating-input resilience |
| 1Q0–1Q7, 2Q0–2Q7 | Data outputs (16 total) | Non-inverting 3-state outputs with integrated 30 Ω series termination for clean edge control |
| 1CP, 2CP | Clock inputs | Rising-edge-triggered clocks for independent latching of each 8-bit section |
| 1OE, 2OE | Output enable (active LOW) | Independent 3-state control per section; enables time-multiplexed bus sharing |
| VCC (pins 7, 18, 31, 42) | Power supply | Four distributed supply pins reduce IR drop and improve noise immunity across wide die |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins provide low-inductance return paths and minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω output termination | Eliminates need for 32 discrete 30 Ω SMT resistors in 16-bit bus designs, saving board space and assembly cost |
| Bus-hold on all data inputs | Maintains last-valid logic state on unused or unterminated D inputs, preventing metastability and system glitches |
| Live insertion/extraction support | Enables hot-swap capability in backplane or modular systems without power cycling or signal disruption |
| 5 V tolerant inputs | Accepts 0–5.5 V input signals while operating at 3.3 V VCC, simplifying mixed-voltage interface design |
| Power-up 3-state and reset | Outputs remain high-impedance until VCC stabilizes, preventing bus contention during power ramp-up |
Applications
| Memory Address Latching | High-Speed Clock Distribution |
|---|---|
|
Use Scenario: Latching 16-bit address bus signals between microcontroller and SRAM/Flash memory. IC Role / Device Role / Timing Role: Edge-triggered register capturing address values synchronously on CPU clock edge for stable memory access timing.

IC Role / Device Role / Timing Role: Fan-out buffer replicating and aligning clock edges across 16 downstream devices using identical propagation path lengths. Use Value: Sub-6 ns tPLH/tPHL matching and 30 Ω series resistance ensure <100 ps inter-output skew and clean edge integrity. |
| Parallel Bus Transceiver Interface | Industrial I/O Expansion |
|
Use Scenario: Bidirectional data transfer between FPGA and legacy 16-bit peripheral bus (e.g., ISA, PC/104). IC Role / Device Role / Timing Role: 3-state-controlled latch providing directionally isolated, noise-immune data capture and drive on shared bus lines. Use Value: ±12 mA drive strength and 5 V-tolerant inputs allow direct connection to 5 V peripherals without level shifters. |
Use Scenario: Expanding GPIO count in PLC or motion controller with deterministic timing and ESD-hardened I/O. IC Role / Device Role / Timing Role: Synchronized input sampling and output update block for real-time digital I/O subsystems. Use Value: Bus-hold inputs prevent spurious triggering on unterminated sensor lines; JESD78B Class II latch-up protection ensures field reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit edge-triggered D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16374ADGGR | No integrated termination; requires external 30 Ω resistors per output; lower drive (±24 mA); 1.65–3.6 V VCC range | Lacks on-die termination and bus-hold; suitable only where external resistor placement is acceptable and wider voltage range is needed | Select when broader VCC range or higher drive is prioritized over board area and signal integrity simplicity |
| 74ALVCH162374T | Higher speed (200 MHz max); no bus-hold; 3.3 V only; different pinout (TSSOP48 but incompatible mapping) | Not pin-compatible; requires PCB redesign; lacks bus-hold, increasing risk of floating-input faults | Choose only for performance-critical designs where 50 MHz+ frequency headroom justifies layout change and added design validation |
Compared with SN74LVC16374ADGGR and 74ALVCH162374T, the 74LVT162374DL,118 uniquely combines on-die 30 Ω termination, bus-hold inputs, and pin-compatible 3.3 V operation-reducing component count, improving noise immunity, and accelerating time-to-market for industrial bus interfaces.

FAQ
Does the 74LVT162374DL,118 support hot-plug operation?
Yes. The device supports live insertion and extraction per its datasheet specification, enabled by power-up 3-state behavior, bus-hold inputs, and ESD-hardened I/O structure. This allows safe module replacement in powered-backplane systems without disrupting adjacent circuitry or causing bus contention.
Can the 74LVT162374DL,118 drive 5 V logic inputs directly?
Yes. Its inputs are 5 V tolerant (VI up to 5.5 V), and outputs deliver VOH ≥ 2.0 V at -12 mA into 3.3 V systems-sufficient to meet TTL HIGH-level input requirements. However, direct connection to 5 V CMOS inputs may require verification of VIH thresholds, as VOH does not reach 5 V.
What is the purpose of the 30 Ω series termination on each output?
The 30 Ω resistor is integrated into each output driver stage to match typical PCB trace impedances (40–70 Ω). It damps signal reflections at the source, reducing overshoot, undershoot, and ringing-critical for maintaining signal integrity in high-speed parallel buses like memory address or data lines.
How does bus-hold functionality affect unused input pins?
Bus-hold circuitry actively maintains the last-seen logic state on any D input with no external bias. For example, if an input floats HIGH, ~75 μA current pulls it toward VCC; if it floats LOW, ~−75 μA pulls it toward GND-preventing oscillation, EMI, and false triggering without external pull-up/down resistors.
