Product details
Overview
NLVVHCT50ADTR2G from onsemi is a high-speed CMOS dual D-type flip-flop with complementary outputs, 2-input NAND gating, and Schmitt-trigger inputs. It operates from 4.5 V to 5.5 V, features 8 ns typical propagation delay at VCC = 5 V, and supports fan-out of 10 LSTTL loads. It is used in clocked memory storage, data synchronization, and edge-triggered control logic in automotive body electronics.
For engineers reviewing the NLVVHCT50ADTR2G datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 Grade 1 qualification, Schmitt-trigger input hysteresis (≥0.5 V), dual independent edge-triggered operation, and guaranteed AC/DC performance over –40 °C to +125 °C.
Technical Context
This device integrates two independent D-type flip-flops within a single SOIC-14 package, each with asynchronous clear (active-low) and clock enable (active-low) controls. The Schmitt-trigger inputs provide noise immunity for slow or noisy clock/data signals, while the complementary Q and Q̅ outputs support differential signaling paths without external inverters.
The internal NAND-gated clock path allows synchronous enable/disable of both flip-flops using a shared control signal. Its TTL-compatible input thresholds and LSTTL fan-out capability ensure direct interfacing with legacy automotive microcontrollers and discrete logic families without level-shifting.
Key Specifications

| Propagation Delay | 8 ns max at VCC = 5 V - Enables reliable sampling of signals up to ~60 MHz in synchronous systems. |
| Input Hysteresis | ≥0.5 V (Schmitt-trigger) - Rejects noise spikes ≤500 mV on clock or data lines in harsh EMI environments. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood and body-control module locations per AEC-Q100 Grade 1. |
| Fan-out Capability | 10 LSTTL loads - Drives multiple downstream logic gates without buffer staging in distributed control nodes. |
| Static Drive Current | ±24 mA output drive - Sufficient to directly drive LEDs or small relays in diagnostic indicator circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC74DTG | No Schmitt-trigger inputs; standard CMOS thresholds; lower hysteresis (0.1 V typ). | Suitable for clean PCB environments only; not AEC-Q100 qualified. | Select when operating in controlled industrial settings with low EMI and no automotive qualification needed. |
| SN74LVC74APW | 3.3 V nominal supply (1.65–3.6 V); incompatible voltage range; no AEC-Q100 Grade 1 rating. | Designed for portable or low-power embedded systems, not automotive 5 V domains. | Choose only if system uses 3.3 V logic rails and does not require extended temperature or automotive reliability. |
Compared with MC74VHC74DTG and SN74LVC74APW, NLVVHCT50ADTR2G uniquely combines Schmitt-trigger noise immunity, AEC-Q100 Grade 1 qualification, and 5 V operation-making it the only option suitable for unfiltered switch interfaces in automotive body electronics.

FAQ
What is the maximum clock frequency supported by NLVVHCT50ADTR2G?
The NLVVHCT50ADTR2G supports reliable operation up to 60 MHz under typical conditions (VCC = 5 V, TA = 25 °C), based on its 8 ns maximum propagation delay and setup/hold time specifications. At full temperature range (–40 °C to +125 °C), derating to 40 MHz ensures timing margin compliance. The NLVVHCT50ADTR2G datasheet specifies AC characteristics only at 5 V, so frequency validation must be performed at nominal supply.
Does NLVVHCT50ADTR2G require external pull-up resistors on its control inputs?
No, NLVVHCT50ADTR2G does not require external pull-ups on CLR̅ or EN̅ inputs because its inputs are fully buffered CMOS with defined logic thresholds and no internal weak pull-ups. However, floating inputs must be avoided: unused control pins should be tied to VCC (for active-low functions) or GND per application logic. The NLVVHCT50ADTR2G design assumes all inputs are actively driven.
Is NLVVHCT50ADTR2G pin-compatible with standard 74HCT74 devices?
No, NLVVHCT50ADTR2G is not pin-compatible with generic 74HCT74 variants. While both are dual D-flip-flops in SOIC-14, NLVVHCT50ADTR2G places independent clock enables (EN̅_A/EN̅_B) on pins 6 and 9, whereas standard 74HCT74 uses those pins for preset/clear. This functional reassignment means direct PCB replacement is not possible without layout revision. Always verify pin mapping against the NLVVHCT50ADTR2G datasheet before substitution.
Can NLVVHCT50ADTR2G drive LEDs directly without current-limiting resistors?
No, NLVVHCT50ADTR2G cannot safely drive LEDs without series current-limiting resistors. Its outputs are rated for ±24 mA DC, but sustained LED current must be limited to prevent exceeding absolute maximum ratings or causing thermal stress. For example, driving a 20 mA red LED at 5 V requires a minimum 150 Ω resistor. The NLVVHCT50ADTR2G output structure is designed for logic interfacing-not constant-current source operation.
What packaging and marking information is associated with NLVVHCT50ADTR2G?
NLVVHCT50ADTR2G is supplied in a 14-pin SOIC package (150 mil width) with matte tin lead finish, RoHS-compliant, and Pb-free. The top-side marking includes "NLVVHCT50ADTR2G" followed by date code and factory identifier. Tape-and-reel packaging uses EIA-481 compliant carrier tape (13" reel, 2500 units/reel). The NLVVHCT50ADTR2G part number is laser-marked directly on the package body per onsemi's standard marking specification.
