Product details
Overview
SN74LVC1G374YEPR from Texas Instruments is a single D-type flip-flop with 3-state output, designed for 1.65-V to 5.5-V operation. It features positive-edge clock triggering, buffered output-enable (OE), ±24-mA drive at 3.3 V, 4-ns max propagation delay at 3.3 V, and Ioff support for live insertion-used in bus interface buffering and I/O port expansion.
For engineers reviewing the SN74LVC1G374YEPR datasheet, SN74LVC1G374YEPR pinout, SN74LVC1G374YEPR application, or SN74LVC1G374YEPR equivalent, this page delivers verified electrical specs, package mapping to YEP/YZP DSBGA-6, functional timing behavior, and real-world implementation context for high-density logic interfacing.
Technical Context
The SN74LVC1G374YEPR implements edge-triggered storage with synchronous data capture on the rising edge of CLK and independent 3-state control via OE. Its output remains latched during OE assertion, enabling bus hold without affecting internal state.
It supports voltage translation across 1.65–5.5 V VCC, accepts inputs up to 5.5 V regardless of supply, and includes Ioff circuitry that disables outputs during partial power-down to prevent back-drive current-critical for hot-swap and mixed-voltage system design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables interoperability across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains |
| tpd (max) | 4 ns at 3.3 V - ensures sub-5-ns timing margin for high-speed data latching in compact interfaces |
| IOL / IOH | ±24 mA at 3.3 V - drives capacitive loads up to 50 pF without external buffers in I/O port applications |
| Ioff | ±10 μA max - blocks current flow when powered down, supporting safe live insertion in backplane systems |
| ESD Rating | HBM: 2000 V - meets industrial-level robustness requirements for handling and board assembly |
| Operating Temp | –40°C to +85°C - qualified for commercial and extended-temperature embedded control environments |
| Input Voltage | Up to 5.5 V - allows direct connection to 5-V signals even when VCC = 1.8 V, eliminating level shifters |
Pinout & Package
SN74LVC1G374YEPR uses the YEP/YZP 6-ball DSBGA package (0.5-mm pitch, 1.418 × 1.358 mm body), optimized for ultra-compact PCB layouts. Ball assignment follows bottom-view orientation with pin 1 in corner A1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | OE | Active-low output enable - asserts high-impedance state independently of clock/data, preserving latch state |
| 2 (A2) | GND | Ground reference - must be low-impedance connection to minimize noise coupling into sensitive CMOS inputs |
| 3 (B1) | VCC | Power supply - decoupling capacitor (0.1 μF) required within 2 mm for stable switching performance |
| 4 (B2) | CLK | Clock input - rising-edge triggered; minimum pulse width 2.5 ns at 3.3 V ensures reliable sampling |
| 5 (C1) | D | Data input - sampled synchronously on CLK↑; setup/hold times as low as 1.5 ns support high-frequency operation |
| 6 (C2) | Q | 3-state output - driven high/low when OE = L; enters high-Z when OE = H, isolating bus lines |
Key Features
| Feature | Design Value |
|---|---|
| NanoFree™ DSBGA packaging | Die-as-package construction eliminates leadframe, reducing footprint to 1.4 mm² and thermal resistance to 123°C/W |
| Down-translation capability | Accepts 5.5-V inputs while operating at 1.65-V VCC - eliminates external level shifters in mixed-supply systems |
| Live-insertion support | Ioff limits off-state leakage to ±10 μA - prevents damaging back-current during hot-plug events in modular systems |
| Low ICC | 10 μA max quiescent current - enables always-on status monitoring in battery-backed subsystems |
| High drive strength | ±24 mA at 3.3 V - directly drives terminated transmission lines or multiple CMOS inputs without fanout buffers |
Applications
| Industrial I/O Expansion | Low-Power Sensor Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop with 3-state output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G74YEPR | Dual-edge triggered D flip-flop (no 3-state output); identical YZP package and VCC range | Lacks OE control - unsuitable for bus sharing; requires external tri-state buffer if used in multiplexed I/O | Select only when synchronous dual-edge sampling is needed and bus isolation is handled elsewhere |
| SN74LVC1G373YEPR | Latch (transparent, level-sensitive) instead of edge-triggered flip-flop; same pinout and drive strength | Requires continuous EN assertion during data window - less suitable for clock-synchronized capture in burst-mode systems | Prefer for simple data capture where clock edge timing is unavailable or asynchronous strobes are used |
Compared with SN74LVC1G374YEPR, SN74LVC1G74YEPR trades 3-state flexibility for dual-edge functionality, while SN74LVC1G373YEPR replaces clock-edge control with level-sensitive gating-both require layout or firmware changes to replace the SN74LVC1G374YEPR's precise edge-triggered + tri-state behavior.

FAQ
What is the maximum clock frequency supported by SN74LVC1G374YEPR?
The SN74LVC1G374YEPR supports up to 175 MHz at 5 V and 150 MHz at 3.3 V under recommended conditions (–40°C to 85°C, CL = 15 pF). At 3.3 V with 50-pF load, fmax drops to 150 MHz due to increased propagation delay-designers should verify timing margins using the tpd and tw values from the switching characteristics table in the official datasheet for SN74LVC1G374YEPR.
Does SN74LVC1G374YEPR support 5-V input tolerance when VCC = 1.8 V?
Yes, SN74LVC1G374YEPR accepts input voltages up to 5.5 V regardless of VCC level, including at 1.8 V. This allows direct interfacing with legacy 5-V peripherals without external level shifters. The input structure is designed for down-translation, and VIH/VIL thresholds scale with VCC-ensuring correct logic interpretation across the full 1.65–5.5-V supply range for SN74LVC1G374YEPR.
How is the output disabled in SN74LVC1G374YEPR, and what happens to the stored data?
In SN74LVC1G374YEPR, the output is disabled by driving OE high, placing Q in high-impedance state. Critically, OE has no effect on internal flip-flop operation: the stored D value remains latched and unchanged. New data can still be clocked in while OE is high, and the previous Q state is preserved-enabling seamless bus arbitration without data loss during SN74LVC1G374YEPR operation.
What package type does SN74LVC1G374YEPR use, and is it compatible with standard SMT processes?
SN74LVC1G374YEPR uses the YZP 6-ball DSBGA package (1.418 × 1.358 mm, 0.5-mm pitch), qualified for standard reflow soldering per JEDEC J-STD-020 (MSL Level-1, peak 260°C). Its NanoFree construction eliminates wire bonds and leadframe, enabling compatibility with fine-pitch stencil printing and automated optical inspection-verified in TI's package materials documentation for SN74LVC1G374YEPR.
Can SN74LVC1G374YEPR be used in automotive applications?
The standard SN74LVC1G374YEPR is rated for –40°C to +85°C and is not AEC-Q200 qualified. For automotive use, TI offers the pin-compatible SN74LVC1G374-Q1 variant, which undergoes extended reliability testing and operates from –40°C to +125°C. Designers requiring automotive qualification must specify SN74LVC1G374-Q1-not SN74LVC1G374YEPR-as the latter lacks the required stress screening and failure rate validation for vehicle systems.
