Nexperia USA Inc. 74LVC2G74DP,125

Overview

74LVC2G74DP from Nexperia is a single positive-edge-triggered D-type flip-flop with asynchronous set (SD) and reset (RD) inputs, complementary Q and Q̅ outputs, 1.65 V to 5.5 V supply range, ±24 mA output drive at 3.0 V, and IOFF partial power-down support. It functions as a synchronous storage element in digital control logic, clock domain interfacing, and level translation between 3.3 V and 5 V systems.

For engineers reviewing the 74LVC2G74DP datasheet, 74LVC2G74DP pinout, 74LVC2G74DP application, or 74LVC2G74DP equivalent, this device is selected for edge-triggered data latching in mixed-voltage industrial controllers, low-power sensor interface timing chains, and robust asynchronous reset-critical state machines where Schmitt-trigger input tolerance and guaranteed -40 °C to +125 °C operation are required.

Technical Context

This flip-flop implements a master-slave D latch architecture synchronized to the LOW-to-HIGH transition of CP, with independent active-low asynchronous SD and RD inputs that override clocked behavior. Its IOFF circuit disables outputs during power-down to prevent backflow current, and Schmitt-trigger inputs accept slow-rising signals up to 20 ns/V (at 1.65 V) or 10 ns/V (at 5.5 V).

Propagation delay ranges from 1.0 ns (at 5.5 V) to 13.4 ns (at 1.65 V), with setup time as low as 1.1 ns and hold time of 1.0 ns at 5.5 V. Maximum operating frequency reaches 200 MHz at 5.5 V and 175 MHz at 3.3 V, supporting high-speed digital control loops and sampling synchronization.

FAQ

What is the minimum pulse width required on CP, SD, or RD inputs?

The minimum pulse width (tW) is 1.0 ns for CP and 1.9 ns for SD/RD at VCC = 5.5 V, increasing to 6.2 ns for CP and 2.7 ns for SD/RD at VCC = 1.65 V. These values ensure reliable edge detection and state transition across the full voltage and temperature range.

Can 74LVC2G74DP safely interface a 5 V microcontroller with a 3.3 V FPGA?

Yes - its overvoltage-tolerant inputs accept 5.5 V regardless of VCC, and its 1.65–5.5 V supply range allows operation at 3.3 V while receiving 5 V logic levels. No external level shifter is needed, simplifying interconnect and reducing signal propagation delay.

How does IOFF function during partial power-down?

When VCC = 0 V, the IOFF circuit places both Q and Q̅ outputs in high-impedance state, preventing reverse current flow from powered downstream circuits into the unpowered flip-flop. This protects against latch-up and ensures clean power sequencing in multi-rail systems.

Is the 74LVC2G74DP pin-compatible with other 74LVC2G74 variants?

No - the 74LVC2G74DP (TSSOP8/SOT505-2) has different pinout than VSSOP8 (74LVC2G74DC), XSON8 (74LVC2G74GT/GN/GS), and older packages. Pin mapping differs significantly (e.g., RD is pin 6 in DP but pin 3 in GT), requiring PCB layout revision for substitution.
