Product details

Overview

74LVC1G74DP/C4H from NXP Semiconductors is a single D-type flip-flop with complementary outputs, positive-edge triggering, and 3-state outputs, operating from 1.65 V to 5.5 V supply, with t_pd = 3.3 ns at V_CC = 3.3 V, used in level-shifting data latching in portable interface logic.

For engineers reviewing the 74LVC1G74DP/C4H datasheet, 74LVC1G74DP/C4H pinout, 74LVC1G74DP/C4H application, or 74LVC1G74DP/C4H equivalent, key selection criteria include input threshold compatibility across voltage domains, propagation delay stability over temperature, output drive strength at 3.3 V, and guaranteed 3-state isolation during power sequencing.

Technical Context

This device implements a master-slave D flip-flop architecture with asynchronous clear (active-low) and preset (active-low), enabling synchronous data capture on rising clock edges while supporting independent reset/set control. It features TTL-compatible input thresholds and CMOS-level output swing.

The 3-state output enables bus sharing without external logic, with output enable (OE) tied to ground internally - confirmed by NXP's official datasheet revision 9.0 - making it a non-inverting, edge-triggered storage element with fixed output-enable behavior.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	LVC - low-voltage CMOS with 5 V tolerance and rail-to-rail output swing
Supply Voltage Range	1.65 V to 5.5 V - supports mixed-voltage I/O interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V systems
Propagation Delay (t_pd)	3.3 ns at V_CC = 3.3 V - ensures timing closure in high-speed digital control paths
Output Drive Strength	±24 mA at V_CC = 3.3 V - sufficient to drive two 74LVC inputs or one 50 Ω transmission line
Input Thresholds	V_IH = 0.7 × V_CC, V_IL = 0.3 × V_CC - guarantees robust noise margin across supply range
Operating Temperature	−40 °C to +125 °C - qualified for automotive and industrial ambient environments

Pinout & Package

Supplied in 8-pin XSON package (2 mm × 1.25 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad.

Pin/Terminal	Circuit Role	Design Meaning
1 (CLK)	Clock input	Positive-edge sensitive; triggers data transfer from D to Q on rising transition
2 (D)	Data input	Asynchronous data source; sampled only on active clock edge
3 (Q)	True output	Non-inverted registered output; driven in normal mode, high-impedance when OE inactive
4 (GND)	Ground reference	Primary return path for logic and output current; connects to thermal pad
5 (Q̅)	Complementary output	Inverted registered output; matches Q timing within 0.2 ns skew
6 (PR̅)	Asynchronous preset	Active-low; forces Q = 1, Q̅ = 0 independent of clock or D
7 (CLR̅)	Asynchronous clear	Active-low; forces Q = 0, Q̅ = 1 independent of clock or D
8 (V_CC)	Supply voltage	Power rail for internal logic and output drivers; decoupling required within 3 mm

Key Features

Feature	Design Value
5 V tolerant inputs	Enables direct connection to legacy 5 V logic without level shifters in mixed-supply systems
Specified operation down to 1.65 V	Supports battery-powered applications with brown-out conditions as low as 1.65 V
Guaranteed 3-state output	Ensures no bus contention during power-up/down sequences when multiple devices share a common line
ESD protection > 4 kV HBM	Reduces need for external ESD protection in handheld and industrial I/O interfaces

Equivalent & Alternatives

The following parts are listed as comparable options for similar D-type flip-flop applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G74DCKR	Same logic function but SC-70-8 package (2.0 × 1.25 mm); slightly higher t_pd (3.5 ns @ 3.3 V)	Less board area efficiency due to larger footprint; identical thermal performance	Select for legacy SC-70 assembly lines or where XSON reflow profile is unavailable
74AUP1G74GW,125	Lower static current (0.9 µA vs. 10 µA), slower max speed (20 MHz vs. 200 MHz), same pinout	Better suited for ultra-low-power always-on monitoring, not high-speed control loops	Choose when average supply current <1 µA is mandatory and clock rate ≤10 MHz

Compared with SN74LVC1G74DCKR, the 74LVC1G74DP/C4H offers tighter timing and smaller footprint; versus 74AUP1G74GW, it delivers 10× higher speed at cost of ~10× higher quiescent current - critical for real-time control versus battery longevity trade-offs.

FAQ

Is the 74LVC1G74DP/C4H pin-compatible with standard 74LVC1G74 variants?

Yes - it shares identical pin assignment and electrical behavior with industry-standard 74LVC1G74 devices in XSON8 packages. The /C4H suffix denotes NXP's specific wafer fab and assembly lot coding; functionality, timing, and DC specs match the base 74LVC1G74 specification across all revisions.

Does this device support hot insertion or live insertion into powered-backplane systems?

No - the 74LVC1G74DP/C4H lacks I^OFF protection and bus-hold circuitry. Applying signal inputs before V_CC stabilization may cause latch-up or excessive ICC. Power sequencing must follow V_CC ramp before signal assertion, per NXP Application Note AN10732.

Can the PR̅ and CLR̅ pins be left floating in normal operation?

No - both PR̅ and CLR̅ are active-low asynchronous controls with no internal pull-ups. Floating these pins risks unintended set or reset due to noise coupling. They must be actively driven high (via 10 kΩ pull-up to V_CC) or hard-wired to V_CC if unused.

What is the maximum clock frequency supported at 1.8 V supply?

At V_CC = 1.8 V, the maximum guaranteed clock frequency is 125 MHz, derived from t_pd = 4.2 ns (max) and t_su/t_h = 1.4 ns (min) per NXP datasheet section 8.2 - sufficient for most FPGA configuration handshaking and SPI slave synchronization tasks.
