Product details

Overview

74LVT16374ADGG,512 from Nexperia is a 3.3 V 16-bit edge-triggered D-type flip-flop with 3-state outputs, designed for high-speed bus interface and data latching in industrial and telecom systems. It features dual independent 8-bit sections (1CP/1OE and 2CP/2OE), 2.7–3.6 V supply range, ±64 mA output drive, and overvoltage-tolerant inputs up to 5.5 V.

For engineers reviewing the 74LVT16374ADGG,512 datasheet, 74LVT16374ADGG,512 pinout, 74LVT16374ADGG,512 application, or 74LVT16374ADGG,512 equivalent, key selection criteria include clock-to-output propagation delay (≤5.0 ns at 3.3 V), set-up/hold timing (0.8 ns / 0.1 ns), bus-hold input capability, and TSSOP48 package compatibility with dense PCB layouts.

Technical Context

This device implements two independent 8-bit positive-edge-triggered D-flip-flop banks, each with dedicated clock (1CP/2CP) and 3-state enable (1OE/2OE). Outputs respond only on LOW-to-HIGH transitions, and OE assertion places outputs in high-impedance without affecting internal register state.

It uses BiCMOS technology to achieve TTL-compatible input thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V) while operating from a 3.3 V supply, enabling direct interfacing with both 3.3 V logic and legacy 5 V buses without level shifters.

Key Specifications

Max clock frequency	150 MHz - enables high-throughput data capture in backplane and memory interface applications
t_PLH/t_PHL	1.5–5.0 ns - ensures sub-5 ns timing margin for 200 Mbps+ parallel bus designs
Set-up / hold time	0.8 ns / 0.1 ns at 3.3 V - permits tight timing closure with fast microcontrollers and FPGAs
Output drive	+64 mA / –32 mA - drives heavy capacitive loads (e.g., 50 pF buses) without external buffers
Input overvoltage	Up to 5.5 V - allows safe connection to 5 V systems without clamping diodes or resistors
Operating temperature	–40 °C to +85 °C - qualified for extended industrial environments

Pinout & Package

TSSOP48 plastic thin shrink small outline package (SOT362-1), 48-pin, 6.1 mm body width, 0.5 mm pitch - optimized for automated assembly and thermal performance in space-constrained boards.

Pin/Terminal	Circuit Role	Design Meaning
1OE, 2OE (Pins 1, 24)	Active-low 3-state enable	Independent control of first/second 8-bit output banks; HIGH disables outputs to high-Z
1CP, 2CP (Pins 48, 25)	Positive-edge clock input	Triggers synchronous capture of D-inputs on rising edge; no internal synchronization
1D0–1D7 (Pins 47, 46, 44, 43, 41, 40, 38, 37)	Data inputs (Bank 1)	Sampled on 1CP rising edge; bus-hold enabled to prevent floating states
2D0–2D7 (Pins 36, 35, 33, 32, 30, 29, 27, 26)	Data inputs (Bank 2)	Sampled on 2CP rising edge; identical electrical behavior to Bank 1
1Q0–1Q7 (Pins 2, 3, 5, 6, 8, 9, 11, 12)	Tri-state outputs (Bank 1)	Driven only when 1OE = LOW; high-Z otherwise; supports hot-swap and bus sharing
2Q0–2Q7 (Pins 13, 14, 16, 17, 19, 20, 22, 23)	Tri-state outputs (Bank 2)	Driven only when 2OE = LOW; electrically isolated from Bank 1 outputs
VCC (Pins 7, 18, 31, 42)	Power supply	Four dedicated 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 for high-speed switching currents

Key Features

Feature	Design Value
Dual 8-bit independent banks	Enables flexible partitioning - e.g., one bank for address latching, another for data strobing
Bus-hold inputs	Eliminates need for external pull-ups on unused D-inputs, reducing BOM count and board area
IOFF partial power-down	Prevents current flow through outputs when VCC = 0 V, supporting live insertion/extraction
Power-up 3-state	Outputs remain high-Z until VCC stabilizes, preventing bus contention during power ramp
Overvoltage-tolerant I/O	Withstands 5.5 V on inputs/outputs while powered from 3.3 V - simplifies mixed-voltage system design

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	Lower drive (+24 mA / –24 mA); 1.65–3.6 V supply; no bus-hold	Suitable for low-power, low-noise applications where 5 V tolerance is not required	Select when cost and power efficiency outweigh drive strength and mixed-voltage robustness
74LVCH16374APAG	Higher drive (+32 mA / –32 mA); includes bus-hold; 2.7–3.6 V; same pinout	Drop-in replacement with identical functionality but improved ESD rating (HBM 8 kV)	Preferred for new designs requiring enhanced latch-up immunity and higher reliability in noisy environments

Compared with SN74LVC16374ADGGR, the 74LVT16374ADGG,512 delivers 2.7× stronger sink current and 5.5 V tolerance - critical for driving legacy 5 V buses. Versus 74LVCH16374APAG, it trades slightly lower ESD rating for proven field reliability and broader temperature validation across –40 °C to +85 °C.

FAQ

What is the maximum clock frequency supported by the 74LVT16374ADGG,512?

The device supports a maximum clock frequency of 150 MHz at V_CC = 3.3 V ± 0.3 V, as specified in Table 7 of the datasheet. This value is measured under standard load conditions (50 pF, 500 Ω), and actual achievable frequency depends on PCB layout, termination, and signal integrity. It is not characterized beyond 150 MHz.

Does the 74LVT16374ADGG,512 support hot-swap operation?

Yes - IOFF circuitry ensures that outputs remain in high-impedance when V_CC = 0 V, and power-up 3-state prevents bus contention during insertion. The device is explicitly rated for live insertion and extraction per Section 2 of the datasheet, provided supply sequencing and slew rate limits are observed.

Can the 74LVT16374ADGG,512 be used with a 5 V microcontroller interface?

Yes - its inputs tolerate up to 5.5 V regardless of V_CC, and outputs drive 5 V buses directly due to overvoltage-tolerant structure. No level-shifting components are needed, though output voltage swing remains limited to V_CC (3.3 V) unless externally pulled up.

How does bus-hold functionality work on this device?

Bus-hold circuitry actively maintains the last valid logic state on unused D-inputs using weak feedback transistors (IBHL = 75–135 μA at 3 V). This eliminates external pull-up/pull-down resistors and prevents floating inputs from causing undefined outputs or increased power consumption.
