Product details
Overview
74ALVCH16374DL,118 from Nexperia is a 16-bit edge-triggered D-type flip-flop with dual independent clock and output-enable control, bus hold inputs, 3-state outputs, and IOFF partial power-down support. It operates across 1.2 V to 3.6 V supply, delivers ±24 mA drive at 3.0 V, and functions as two 8-bit or one unified 16-bit register in industrial bus interface and data latching applications.
For engineers reviewing the 74ALVCH16374DL,118 datasheet, 74ALVCH16374DL,118 pinout, 74ALVCH16374DL,118 application, or 74ALVCH16374DL,118 equivalent, key selection considerations include dual-clock timing isolation, bus hold input stability without external pull-ups, IOFF-enabled safe power sequencing, and TSSOP48 package compatibility with high-density PCB layouts.
Technical Context
This device implements two independent 8-bit D-flip-flop banks-each with dedicated clock (1CP/2CP) and 3-state output enable (1OE/2OE)-enabling asynchronous latching of parallel data streams. Bus hold circuitry maintains valid logic states on all 16 D-inputs during floating conditions, eliminating external bias resistors.
The IOFF feature actively disables outputs when VCC drops below threshold, blocking backflow current during partial power-down sequences. Propagation delay is 1.0 ns (typ) to 3.4 ns (max) at 3.0–3.6 V, with setup/hold times as tight as 1.2 ns / 0.8 ns for reliable high-speed capture at up to 350 MHz maximum frequency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - supports mixed-voltage system interfacing and low-power operation down to 1.2 V logic. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - directly drives 50 Ω transmission lines without external buffers at 85 °C. |
| Propagation Delay | 1.0–3.4 ns (VCC = 3.0–3.6 V) - enables reliable 350 MHz operation in high-speed data capture paths. |
| Set-up / Hold Time | 1.2 ns / 0.8 ns (VCC = 3.0–3.6 V) - ensures robust sampling margin for fast synchronous buses. |
| IOFF Support | Yes - prevents destructive back-current during partial power-down, critical for hot-swap and multi-rail systems. |
| Bus Hold Input | Integrated on all 16 D-inputs - eliminates need for external pull-up/down resistors, reducing BOM count and layout area. |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial ambient environments without derating. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE (Pins 1, 24) | Active-low output enable | Independently disables 8-bit output banks into high-impedance state without affecting internal flip-flop state. |
| 1CP, 2CP (Pins 48, 25) | LOW-to-HIGH edge-triggered clock | Each controls latching of its associated 8-bit D-input bank; clocks are electrically isolated. |
| 1D0–1D7 (Pins 47, 46, 44, 43, 41, 40, 38, 37) 2D0–2D7 (Pins 36, 35, 33, 32, 30, 29, 27, 26) |
Data inputs | All 16 inputs feature integrated bus hold - retains last valid logic level when un-driven. |
| 1Q0–1Q7 (Pins 2, 3, 5, 6, 8, 9, 11, 12) 2Q0–2Q7 (Pins 13, 14, 16, 17, 19, 20, 22, 23) |
3-state outputs | Driven HIGH/LOW or placed in high-Z per bank; output state unaffected by OE deassertion. |
| VCC (Pins 7, 18, 31, 42) | Positive supply | Four distributed VCC pins minimize supply inductance and reduce ground bounce in high-speed switching. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths, critical for noise immunity in dense digital systems. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit banks | Enables time-isolated latching of two data streams (e.g., ADC channel A/B or dual memory ports) using separate clocks and enables. |
| Bus hold on all inputs | Eliminates external pull resistors while maintaining stable logic levels during signal contention or tri-state transitions. |
| IOFF partial power-down | Automatically disables outputs when VCC falls, preventing reverse current flow during power sequencing or hot-plug events. |
| MULTIBYTE™ flow-through pinout | Input/output pairs aligned across package width simplify PCB routing and reduce trace skew in parallel bus implementations. |
| Low-noise power distribution | Four VCC and eight GND pins suppress simultaneous switching noise and ground bounce in high-speed 16-bit interfaces. |
Applications
| Industrial PLC I/O Expansion | High-Speed Memory Interface Buffer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH16374GR | TI part with higher drive (±32 mA), no bus hold, requires external pull resistors; supports 2.3–3.6 V only. | Lacks bus hold and IOFF; suited for fixed-rail systems where external biasing is acceptable. | Select if higher output current is required and bus hold is unnecessary; verify layout accommodates added resistor count. |
| 74LVC16374APAG | IDT (now Renesas) part with identical pinout, same 1.2–3.6 V range, but no IOFF and weaker drive (±24 mA @ 3.3 V only). | No partial power-down protection; less robust for multi-rail sequencing or hot-swap use cases. | Choose when cost sensitivity outweighs IOFF requirement and system power sequencing is fully controlled. |
Compared with SN74ALVTH16374GR and 74LVC16374APAG, the 74ALVCH16374DL,118 uniquely combines bus hold, IOFF, and full 1.2–3.6 V operation in a single industrial-grade device-reducing external components, enabling safer power management, and simplifying design for variable-voltage or modular systems.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74ALVCH16374DL,118?
The device is fully specified from 1.2 V to 3.6 V. At 1.2 V, static and dynamic parameters-including VIH/VIL thresholds, propagation delay, and output drive-are guaranteed across −40 °C to +85 °C per the datasheet's recommended operating conditions and static characteristics tables.
Does the 74ALVCH16374DL,118 require external pull-up or pull-down resistors on its D-inputs?
No. All 16 D-inputs integrate bus hold circuitry, which actively maintains the last valid logic state when inputs are un-driven. This eliminates the need for external bias resistors and reduces board area and BOM cost.
How does the IOFF feature function during partial power-down?
When VCC drops below a threshold, the IOFF circuitry automatically places all outputs in high-impedance state-regardless of OE pin state-preventing reverse current flow from powered sections into the unpowered device, protecting both the IC and system integrity.
Can the 74ALVCH16374DL,118 be used as a single 16-bit register or must it operate as two 8-bit units?
It can operate flexibly as either configuration: tie 1CP and 2CP together and 1OE and 2OE together for unified 16-bit operation, or drive clocks and enables independently to manage two isolated 8-bit data paths-no hardware modification required.
