NXP Semiconductors 74LV74N,112

Overview

74LV74N,112 from NXP Semiconductors is a dual positive-edge-triggered D-type flip-flop with asynchronous active-LOW set (nSD) and reset (nRD) inputs, 1.0 V to 5.5 V supply range, −40 °C to +125 °C operation, and Schmitt-trigger clock inputs for robust timing in noisy environments - used in digital control logic, state machines, and clock-domain synchronization circuits.

For engineers reviewing the 74LV74N,112 datasheet, 74LV74N,112 pinout, 74LV74N,112 application, or 74LV74N,112 equivalent, this page delivers verified functional identity, DIP14 package mapping, timing parameters at multiple VCC levels, ESD ratings, and real-world use context for industrial control and legacy TTL-interfaced systems.

Technical Context

The 74LV74N,112 implements two independent CMOS D-type flip-flops sharing no internal coupling - each features asynchronous nSD/nRD, edge-sensitive nCP, and complementary nQ/nQ outputs. Its Schmitt-trigger clock input enables reliable operation with slow-rising or noisy clock signals across 1.0–5.5 V.

It operates over full industrial temperature range (−40 °C to +125 °C), supports direct TTL-level interfacing at 2.7–3.6 V, and meets HBM ESD >2000 V and MM ESD >200 V per JESD22-A114-A/A115-A standards.

FAQ

What is the maximum clock frequency supported by the 74LV74N,112 at 3.3 V?

The 74LV74N,112 supports a maximum clock frequency of 100 MHz at VCC = 3.3 V under −40 °C to +85 °C conditions, and 48 MHz across the full −40 °C to +125 °C range. This is derived from the minimum clock pulse width (tW) of 7 ns and propagation delay (tpd) of 13 ns max at 3.3 V, ensuring reliable setup/hold timing margins in synchronous designs using the 74LV74N,112.

Does the 74LV74N,112 support true 1.0 V operation, or are DC characteristics only guaranteed above 1.2 V?

The 74LV74N,112 is functionally guaranteed down to VCC = 1.0 V (with inputs referenced to GND or VCC), but DC electrical characteristics - including VIH, VIL, VOH, VOL, and ICC - are fully specified and tested only from VCC = 1.2 V to 5.5 V. At 1.0 V, basic functionality is ensured, but timing and drive strength may vary; design margins should be validated per application when using 74LV74N,112 below 1.2 V.

Can the 74LV74N,112 be used to interface directly with standard 5 V TTL logic?

Yes - the 74LV74N,112 supports direct interface with TTL levels (2.7 V to 3.6 V) per its datasheet, and its output VOH exceeds 2.4 V at VCC = 3.3 V driving 6 mA, meeting TTL HIGH-level input requirements. When powered at 5.0 V, its VOH reaches 4.3 V (min) at 12 mA, fully compatible with 5 V TTL inputs. The 74LV74N,112 thus bridges 3.3 V and 5 V logic domains without level shifters.

What is the purpose of the Schmitt-trigger action on the clock input of the 74LV74N,112?

The Schmitt-trigger action on the 74LV74N,112 clock input provides hysteresis (typically ~0.3 V at 3.3 V), enabling reliable edge detection on slow-rising or noisy clock signals - such as those from RC oscillators, mechanical switch debouncing circuits, or long PCB traces. This eliminates false triggering and eliminates the need for external filtering components, simplifying designs where clock integrity cannot be guaranteed, as confirmed in the 74LV74N,112 functional description.

Is the 74LV74N,112 automotive-qualified?

No - the 74LV74N,112 is not automotive-qualified. Although it operates across −40 °C to +125 °C, NXP explicitly states in its legal disclaimers that non-automotive qualified products like the 74LV74N,112 are neither tested nor warranted for automotive use. It may be used in non-safety-critical automotive auxiliary functions (e.g., interior lighting controls), but system-level qualification remains the customer's responsibility - and the 74LV74N,112 itself carries no AEC-Q100 rating.
