Product details
Overview
74LVC16374ADGG-Q1J from Nexperia is a 16-bit edge-triggered D-type flip-flop with dual independent clock (1CP/2CP) and output enable (1OE/2OE) control, 3-state outputs, 5 V tolerant inputs, and operation across 1.2 V to 3.6 V supply. It functions as two synchronized 8-bit registers or one unified 16-bit latch in automotive-grade logic interfacing, bus buffering, and data synchronization applications.
For engineers reviewing the 74LVC16374ADGG-Q1J datasheet, 74LVC16374ADGG-Q1J pinout, 74LVC16374ADGG-Q1J application, or 74LVC16374ADGG-Q1J equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, dual-clock domain isolation, IOFF power-down protection, Schmitt-trigger input tolerance, and mixed-voltage (3.3 V/5 V) interface capability.
Technical Context
This device implements two independent 8-bit D-type flip-flop banks, each with dedicated clock and output-enable signals, enabling asynchronous register control without cross-bank timing coupling. Its IOFF circuitry actively disables outputs and blocks backflow current when VCC = 0 V, satisfying partial power-down requirements in automotive domain controllers.
Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), allowing robust operation with slow-rising signals from legacy 5 V TTL sources. Bus hold functionality on data inputs (74LVCH variant) maintains valid logic states during high-impedance bus conditions-though 74LVC16374A lacks bus hold per datasheet Table 6 footnotes.
Key Specifications

|---|---|
| Logic Function | 16-bit edge-triggered D-type flip-flop with dual 8-bit banks and 3-state outputs |
| Supply Voltage Range | 1.2 V to 3.6 V - supports low-power 1.2 V core domains while maintaining 5 V input tolerance |
| Input Voltage Tolerance | Up to 5.5 V - enables direct connection to 5 V buses without level-shifting circuitry |
| Propagation Delay (tpd) | 1.5 ns (min) to 7.0 ns (max) at VCC = 3.0–3.6 V - ensures sub-7 ns timing for 100+ MHz synchronous systems |

Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm pitch, exposed thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE (Pins 1, 24) | Output enable (active LOW) | Independently disables 8-bit output banks into high-impedance state without affecting internal register state |
| 1CP, 2CP (Pins 48, 25) | Clock input (LOW-to-HIGH edge sensitive) | Triggers parallel load of corresponding D-input bank; no internal clock distribution skew between pins |
| 1D0–1D7 (Pins 47, 46, 44, 43, 41, 40, 38, 37) | Data input (Bank 1) | Sampled on rising edge of 1CP; Schmitt-triggered for noise immunity on slow-rising signals |
| 2D0–2D7 (Pins 36, 35, 33, 32, 30, 29, 27, 26) | Data input (Bank 2) | Electrically isolated from Bank 1; supports independent timing domains or redundant data paths |
| 1Q0–1Q7 (Pins 2, 3, 5, 6, 8, 9, 11, 12) | Data output (Bank 1) | 3-state capable; output voltage swing rails to VCC/GND with <0.55 V VOL at 24 mA sink |
| 2Q0–2Q7 (Pins 13, 14, 16, 17, 19, 20, 22, 23) | Data output (Bank 2) | Matched drive strength and timing to Bank 1; output skew ≤1.5 ns between any two outputs |
| VCC (Pins 7, 18, 31, 42) | Supply voltage | Four distributed supply pins minimize IR drop and ground bounce in high-speed switching |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins ensure low-inductance return path for all 32 I/Os and internal logic |

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 | Non-automotive grade; rated -40 °C to +85 °C only; identical pinout and electrical specs except AEC-Q100 qualification | Lacks AEC-Q100 Grade 1 validation; unsuitable for under-hood or safety-critical modules | Select only for non-automotive industrial or consumer designs requiring same functionality at lower cost |
| 74LVCH16374ADGG-Q1J | Includes bus hold on all data inputs (IBHL/IBHH up to ±75 μA); otherwise identical timing, voltage, and packaging | Eliminates need for external pull-up/down resistors on floating data lines in multiplexed bus architectures | Choose when system-level bus contention or un-driven data lines are present; adds ~5% cost premium |
Compared with SN74LVC16374ADGGR, the 74LVC16374ADGG-Q1J provides guaranteed automotive reliability and extended temperature operation, while the 74LVCH16374ADGG-Q1J adds bus hold for passive signal retention-making the base LVC variant optimal for cost-sensitive, thermally stable automotive sub-systems where external biasing is already implemented.

FAQ
Is 74LVC16374ADGG-Q1J pin-compatible with 74LVCH16374ADGG-Q1J?
Yes - both devices share identical TSSOP48 (SOT362-1) pinout, supply voltage range, timing parameters, and functional behavior. The only difference is that the LVCH variant includes bus hold circuitry on data inputs, while the LVC version does not. No PCB redesign is required for substitution, but external pull resistors may be needed if bus hold is relied upon in the design.
What is the maximum clock frequency supported at 125 °C ambient?
The datasheet specifies a minimum fmax of 120 MHz over -40 °C to +125 °C ambient. This is measured under worst-case VCC (3.0 V), load (50 pF), and process corner conditions. At typical VCC = 3.3 V and 25 °C, fmax reaches 150 MHz, but derating to 120 MHz ensures timing margin across full automotive temperature and voltage extremes.
Does this device support hot insertion or live board replacement?
Yes - the IOFF circuitry actively disables outputs and blocks back-current when VCC = 0 V, satisfying IEC 61000-4-2 and ISO 16750-2 requirements for hot-swap compatibility. This allows safe insertion/removal in powered automotive sub-systems such as modular ADAS sensor carriers or reconfigurable ECU daughterboards.
Can 74LVC16374ADGG-Q1J interface directly with 5 V microcontrollers?
Yes - its inputs tolerate up to 5.5 V regardless of VCC level (1.2 V to 3.6 V), enabling direct connection to legacy 5 V MCU GPIOs without level shifters. Outputs swing rail-to-rail (VCC/GND), so interfacing with 5 V receivers requires external pull-up resistors or a compatible 3.3 V–5 V tolerant receiver - the device itself does not drive 5 V logic levels.
