Product details
Overview
CD74AC175M96G4 from Texas Instruments is a quadruple positive-edge-triggered D-type flip-flop with asynchronous clear, designed for synchronous data latching in digital logic systems. It features complementary Q and Q̅ outputs per stage, ±24mA output drive at 4.5–5.5V, 1.5V to 5.5V supply operation, and balanced propagation delays. It is used in buffer/storage register circuits requiring reliable edge-triggered state retention.
For engineers reviewing the CD74AC175M96G4 datasheet, CD74AC175M96G4 pinout, CD74AC175M96G4 application, or CD74AC175M96G4 equivalent, key selection criteria include its 16-pin SOIC package, dual-rail output architecture, 114MHz max clock frequency at 5V, and SCR-latchup-resistant CMOS process suitable for industrial temperature range (–55°C to 125°C).
Technical Context
This device implements four independent D-type flip-flops sharing a common clock (CLK) and global asynchronous clear (CLR) input. Each stage provides true and complemented outputs (Q and Q̅), enabling direct implementation of toggle, latch, and storage functions without external inversion.
It operates across 1.5V–5.5V supply, with timing parameters fully characterized at 1.5V, 3.3V, and 5V. Propagation delay (tPLH/tPHL) ranges from 3.1ns (min) to 12.2ns (max) at 5V/CL=50pF, and setup/hold times are fixed at 2ns/2ns respectively - ensuring robust timing margin in high-speed logic interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | Advanced CMOS (AC), compatible with TTL input thresholds and offering bipolar-speed performance with CMOS power efficiency |
| Supply Voltage Range | 1.5V to 5.5V - enables single-supply operation across 1.8V, 3.3V, and 5V system domains without level translation |
| Max Clock Frequency | 114 MHz at VCC = 5V - supports high-throughput data capture in register files and pipeline stages |
| Output Drive | ±24 mA at VCC = 4.5–5.5V - drives up to 15 F-series logic loads directly, reducing need for buffer stages |
| Propagation Delay | 3.1 ns (min) to 12.2 ns (max) at 5V/CL=50pF - ensures predictable timing in synchronous state machines |
| ESD Protection | ±2000 V HBM - exceeds MIL-STD-883 requirement, supporting robust handling in manufacturing and field environments |
| Operating Temperature | –55°C to +125°C - qualified for extended industrial and automotive under-hood applications |
Pinout & Package
CD74AC175M96G4 is housed in a 16-pin SOIC (D) package measuring 9.9 mm × 6.0 mm (including pins), with body dimensions of 9.9 mm × 3.9 mm. The package is RoHS-compliant, NIPDAU lead finish, MSL Level-1, and optimized for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLR | Asynchronous active-low clear input - resets all four flip-flop outputs to logic low regardless of clock state |
| 2, 3, 6, 7, 10, 11, 14, 15 | Q / Q̅ | Complementary outputs (Q and Q̅) for each of four D-type stages - eliminates need for external inverters in differential signaling paths |
| 4, 5, 12, 13 | D | Data inputs for flip-flops 1–4 - sampled on rising edge of CLK and transferred to outputs synchronously |
| 8 | GND | Ground reference for all internal circuitry and output drivers - must be low-impedance for noise immunity |
| 9 | CLK | Positive-edge-triggered clock input - controls simultaneous sampling of all four D inputs |
| 16 | VCC | Power supply pin - bypassing with 0.1 µF capacitor near pin is required for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Buffered inputs | Reduces capacitive loading and improves noise rejection on CLK and CLR lines, critical for multi-load fanout |
| Double-rail outputs per stage | Provides both Q and Q̅ from each flip-flop - enables direct connection to differential receivers or XOR-based logic without added gates |
| Balanced propagation delays | Minimizes skew between Q and Q̅ transitions, improving timing predictability in feedback or toggle configurations |
| SCR-latchup resistance | Prevents destructive latch-up under transient overvoltage or ESD events - essential for reliability in noisy industrial environments |
| 1.5V–5.5V wide supply range | Supports mixed-voltage system integration (e.g., 1.8V FPGA I/O driving 3.3V logic registers) without external level shifters |
Applications
| Buffer/Storage Registers | Shift Registers |
|---|---|
|
Use Scenario: Holding parallel data from an ADC interface before serial transmission. IC Role / Device Role / Timing Role: Synchronous data latch providing metastability-hardened storage aligned to system clock domain.

IC Role / Device Role / Timing Role: Edge-triggered storage element cascaded via Q→D routing to propagate bits across stages. Use Value: Complementary outputs enable direct driving of common-anode or common-cathode LED segments without additional inverters. |
| Pattern Generators | State Machine Registers |
|
Use Scenario: Generating repeating binary sequences (e.g., 00110100) for test signal injection in embedded diagnostics. IC Role / Device Role / Timing Role: Configured as a 4-bit ring counter or Johnson counter using feedback from Q outputs. Use Value: Asynchronous CLR allows deterministic reset to known initial state, critical for repeatable pattern initialization. |
Use Scenario: Storing current state bits in a finite-state machine controlling motor commutation logic. IC Role / Device Role / Timing Role: Register holding present-state vector updated synchronously on each clock edge. Use Value: ±24mA drive strength supports direct interfacing with gate drivers or optocouplers, eliminating buffer ICs in safety-critical control paths. |
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 |
|---|---|---|---|
| SN74AC175N | Same AC logic family, identical pinout and function, but in PDIP-16 package - lacks SOIC thermal performance and reflow compatibility | Preferred for through-hole prototyping or legacy board repair; not suitable for automated SMT production | Select when manual assembly or socket-based testing is required; verify PCB footprint and thermal derating for continuous operation |
| CD74HC175M | High-speed CMOS (HC) variant - slower max frequency (25 MHz at 6V), lower drive (±4mA), wider VCC range (2–6V) | Better suited for ultra-low-power battery-operated systems where speed is secondary to quiescent current (2 μA typical ICC) | Choose for cost-sensitive, low-speed applications below 20 MHz; avoid where >50 MHz timing or >±12mA drive is needed |
Compared with SN74AC175N and CD74HC175M, CD74AC175M96G4 delivers superior speed-to-power ratio and industrial temperature support in a standard SOIC-16 package - making it optimal for high-reliability, high-throughput digital control subsystems requiring guaranteed timing margins.

FAQ
What is the maximum clock frequency supported by CD74AC175M96G4?
The CD74AC175M96G4 supports a maximum clock frequency of 114 MHz when operated at VCC = 5V ± 0.5V and CL = 50 pF, as specified in Section 5.11 of the official datasheet. At 3.3V, the max frequency drops to 81 MHz, and at 1.5V it is 114 MHz only under specific load conditions - always verify timing margins against actual board capacitance and temperature.
Does CD74AC175M96G4 support 1.8V operation?
Yes, CD74AC175M96G4 supports 1.5V to 5.5V supply operation, including 1.8V nominal systems. At 1.8V, timing parameters such as propagation delay and setup time are interpolated from the 1.5V and 3.3V characterization data - refer to TI's application note SBAA332 for recommended derating guidelines.
How many flip-flops are integrated in CD74AC175M96G4?
CD74AC175M96G4 integrates exactly four independent D-type flip-flops in a single 16-pin SOIC package. Each flip-flop has dedicated D input and complementary Q/Q̅ outputs, with all stages sharing one common CLK and one global CLR input.
What is the purpose of the double-rail outputs in CD74AC175M96G4?
The double-rail (Q and Q̅) outputs in CD74AC175M96G4 eliminate the need for external inverters when implementing differential logic, toggle functions, or feedback paths. This reduces component count, PCB area, and propagation delay skew - especially valuable in synchronous counters and Johnson ring configurations.
Is CD74AC175M96G4 pin-compatible with CD74HC175M?
Yes, CD74AC175M96G4 is pin-compatible with CD74HC175M in the same SOIC-16 package - same pin numbering, function mapping, and power/ground locations. However, AC and HC families differ in speed, drive strength, and voltage thresholds; verify timing and noise margin compatibility before substitution.
