Product details

Overview

74LVC16374ABX,518 from Nexperia is a 16-bit edge-triggered D-type flip-flop with dual independent 8-bit sections, 3-state outputs, 5 V-tolerant inputs, and operation across 1.2 V to 3.6 V supply. It features two clocks (1CP, 2CP), two output enables (1OE, 2OE), and Schmitt-trigger inputs for noise immunity-used in bus interface latching and level translation between 3.3 V and 5 V systems.

For engineers reviewing the 74LVC16374ABX,518 datasheet, 74LVC16374ABX,518 pinout, 74LVC16374ABX,518 application, or 74LVC16374ABX,518 equivalent, this device supports mixed-voltage data capture, high-speed register staging in industrial control backplanes, and noise-robust I/O buffering in telecom line cards where precise setup/hold timing and IOFF power-down protection are required.

Technical Context

This device implements two independent 8-bit positive-edge-triggered D-flip-flop banks, each with dedicated clock and output-enable control. Its IOFF circuitry actively disables outputs when VCC = 0 V, preventing backflow current during partial power-down sequences in hot-swap or multi-rail systems.

Schmitt-trigger inputs ensure reliable operation with slow-rising signals (Δt/ΔV up to 20 ns/V at VCC = 1.65 V), while bus-hold functionality on data inputs (74LVCH variant only) maintains logic state during floating conditions-though 74LVC16374ABX,518 lacks bus hold per datasheet Table 6 footnotes.

Key Specifications

Key Features

Feature	Design Value
Dual 8-bit register architecture	Enables independent clocking and output control of two data groups-ideal for split-bus or channelized I/O

Schmitt-trigger inputs	Accepts slow-rising/falling signals (up to 20 ns/V) without oscillation-improves robustness in noisy industrial environments
IOFF partial power-down	Prevents back-current flow when VCC = 0 V-essential for hot-swap compliance and safe multi-rail sequencing
Low dynamic power dissipation	CPD = 18.5 pF at VCC = 3.3 V-limits switching power in high-density register files and memory interfaces

Applications

Industrial PLC Backplane Interface

Telecom Line Card Data Latching

Use Scenario: Capturing parallel status signals from field I/O modules onto a synchronized backplane bus.

IC Role / Device Role / Timing Role: Edge-triggered register holding 16-bit sensor/actuator status with independent clock enables for staggered sampling.

Use Value: Dual-clock architecture allows time-aligned capture of two 8-bit subsystems without inter-bank skew; IOFF prevents backfeed during module hot-swap.

Use Scenario: Latching configuration data from a management processor to multiple transceiver ASICs on a line card.

IC Role / Device Role / Timing Role: High-speed D-flip-flop providing glitch-free, setup/hold-compliant data staging before distribution to PHY devices.

Use Value: 5 V-tolerant inputs accept management bus signals directly; low propagation delay (≤5.4 ns) ensures tight timing margins in 100+ MHz control paths.

Automotive Body Control Module (Non-Safety)

Test Equipment Digital Pattern Generator

Use Scenario: Buffering and synchronizing switch inputs (door locks, lighting) to a 3.3 V microcontroller in 12 V vehicle electrical environment.

IC Role / Device Role / Timing Role: Level-translating latch isolating MCU from noisy 12 V domain via 5 V-tolerant inputs and 3.3 V-compatible outputs.

Use Value: Schmitt-trigger inputs reject EMI-induced glitches on long harness runs; wide temperature range (-40 °C to +125 °C) meets under-hood requirements.

Use Scenario: Generating precise, skew-controlled digital stimulus patterns for IC functional testing.

IC Role / Device Role / Timing Role: Synchronized register bank delivering deterministic, low-skew (≤1.0 ns) parallel output waveforms.

Use Value: Output skew specification guarantees timing alignment across all 16 bits-critical for vector accuracy in ATE applications.

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
SN74LVC16374ADGGR	Same function, TSSOP48 package, but TI-specified 1.65 V–3.6 V VCC range (Nexperia supports 1.2 V–3.6 V)	Lacks IOFF circuit-unsuitable for partial power-down or hot-swap scenarios requiring VCC = 0 V isolation	Select when full 1.2 V operation is unnecessary and TI ecosystem compatibility is prioritized.
74LVCH16374ADGG	Identical pinout and timing, but adds bus-hold on data inputs (IBHL/IBHH specified); same IOFF and voltage specs	Bus-hold eliminates need for external pull-ups on unused data lines-reduces component count in sparse I/O designs	Select when input floating states must be actively maintained without external resistors, especially in low-pin-count FPGA interfaces.

Compared with SN74LVC16374ADGGR, the 74LVC16374ABX,518 offers broader voltage support and critical IOFF protection; versus 74LVCH16374ADGG, it trades bus-hold capability for marginally lower static current and identical core register functionality.

FAQ

Does 74LVC16374ABX,518 support 1.2 V operation?

Yes. The device is fully specified from 1.2 V to 3.6 V supply voltage, with guaranteed timing and DC parameters across that range-including propagation delay ≤14 ns at VCC = 1.2 V and VIH/VIL thresholds scaled accordingly. This enables direct use with 1.2 V FPGAs and ultra-low-power MCUs.

Is bus-hold functionality present on 74LVC16374ABX,518?

No. Bus-hold (IBHL/IBHH) is exclusive to the 74LVCH16374A variant, as confirmed in datasheet Section 2 ("Features and benefits") and Table 6 footnotes. The 74LVC16374A version lacks internal bus-hold circuitry on data inputs and requires external pull-up/pull-down resistors if inputs may float.

What is the maximum clock frequency supported?

At VCC = 3.3 V and TA = 25 °C, fmax is 300 MHz (typical) with a guaranteed minimum of 120 MHz over -40 °C to +125 °C. This is derived from tW (clock pulse width) ≥3.0 ns and tpd ≤5.4 ns, enabling reliable operation in high-speed control and test equipment applications.

How does IOFF protect during power-down?

When VCC = 0 V, the IOFF circuitry forces all outputs into high-impedance state regardless of OE or CP state-preventing reverse current flow from powered downstream buses into the unpowered device. This meets JEDEC JESD78 requirements for safe multi-rail sequencing and hot-swap operation.
