Product details
Overview
CD74AC175M96E4 from Texas Instruments is a quadruple positive-edge-triggered D-type flip-flop with asynchronous clear (CLR), complementary Q/Q̅ outputs per stage, ±24mA output drive, 1.5V–5.5V supply operation, and balanced propagation delays. It serves as a synchronous storage element in digital control logic, register files, and pattern generation circuits operating across industrial temperature ranges (–55°C to 125°C).
For engineers reviewing the CD74AC175M96E4 datasheet, CD74AC175M96E4 pinout, CD74AC175M96E4 application, or CD74AC175M96E4 equivalent, this page delivers verified functional role, SOIC-16 pin mapping, timing behavior at 1.5V/3.3V/5V, ESD robustness (±2kV HBM), and real-world substitution guidance for logic register design.
Technical Context
The CD74AC175M96E4 implements four independent D-type latches triggered on the rising edge of CLK, each with active-low asynchronous CLR and dual-rail outputs. Its CMOS process ensures SCR-latchup resistance and operation down to 1.5V while maintaining TTL-compatible noise margins (30% VCC).
Timing is characterized across three supply rails: max clock frequency reaches 114 MHz at 5V, 81 MHz at 3.3V, and 114 MHz at 1.5V (with relaxed load); propagation delays (tPLH/tPHL) range from 3.1 ns (5V) to 153 ns (1.5V) into 50-pF loads, with consistent 2 ns setup/hold times regardless of VCC or temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Type | Quadruple D-type flip-flop with asynchronous clear and complementary outputs |
| Supply Voltage Range | 1.5V to 5.5V - enables direct interface with mixed-voltage systems (1.8V, 3.3V, 5V logic domains) |
| Output Drive | ±24mA - supports fanout to 15 F-series devices or direct driving of moderate-capacitance buses |
| Max Clock Frequency | 114 MHz at VCC = 5V - suitable for high-speed register transfer in control state machines |
| ESD Rating | ±2000V HBM - meets MIL-STD-883 requirement for robust handling in manufacturing and field environments |
| Operating Temperature | –55°C to 125°C - qualified for under-hood automotive, industrial PLC, and aerospace subsystems |
| Propagation Delay | 3.1 ns (tPLH/tPHL, VCC = 5V, CL = 50pF) - enables tight timing closure in synchronous pipelines |
Pinout & Package
CD74AC175M96E4 is housed in a 16-pin SOIC (D) package measuring 9.9 mm × 6.0 mm (body: 9.9 mm × 3.9 mm), RoHS-compliant with NIPDAU lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | CLR | Active-low asynchronous reset - forces all Q outputs low regardless of clock or data state |
| 2,3 | 1Q, 1Q̅ | Complementary outputs of first flip-flop - eliminates need for external inverters in toggle or latch applications |
| 4 | 1D | Data input for first flip-flop - sampled on rising CLK edge if CLR is high |
| 5,12,13 | 2D, 3D, 4D | Independent data inputs for remaining three flip-flops - supports parallel loading of 4-bit words |
| 6,7,10,11,14,15 | 2Q, 2Q̅, 3Q, 3Q̅, 4Q, 4Q̅ | Full complementary output set - enables differential signaling or dual-rail logic without external gates |
| 8 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling |
| 9 | CLK | Global positive-edge clock - synchronizes all four flip-flops simultaneously |
| 16 | VCC | Power supply - requires local 0.1 µF bypass capacitor per TI layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Buffered inputs | Reduces capacitive loading on upstream drivers and improves noise immunity across voltage rails |
| Balanced propagation delays | Minimizes skew between Q and Q̅ outputs - critical for glitch-free enable/disable in bus transceivers |
| SCR-latchup-resistant CMOS | Prevents destructive latch-up during transient overvoltage events in industrial power environments |
| 1.5V–5.5V operation | Eliminates level-shifting requirements when interfacing with legacy 5V microcontrollers and modern 1.8V FPGAs |
| Double-rail outputs per stage | Provides native true/complement signals - reduces component count in Johnson counters and shift-register feedback paths |
Applications
| Buffer/Storage Registers | Shift Registers |
|---|---|
Use Scenario: Holding 4-bit configuration data in an FPGA configuration manager during power-up sequencing. IC Role / Device Role / Timing Role: Synchronous storage element capturing parallel data on CLK edge; CLR initializes registers to known state before system boot. Use Value: Complementary outputs eliminate need for external inverters in status flag decoding, reducing board area and signal path delay. |
Use Scenario: Implementing a 4-bit serial-in/parallel-out shift register for LED matrix column addressing. IC Role / Device Role / Timing Role: Edge-triggered data capture and stage-to-stage propagation; CLK advances bits through Q outputs to next stage's D input. Use Value: ±24mA drive directly sources common-anode LED columns without external buffers, simplifying BOM and layout. |
| Pattern Generators | Digital Control State Machines |
Use Scenario: Generating repeating 4-bit test patterns (e.g., 0001 → 0010 → 0100 → 1000) for memory controller verification. IC Role / Device Role / Timing Role: Clocked register feeding combinational logic that computes next pattern; CLR resets sequence on error detection. Use Value: Balanced tPLH/tPHL ensures deterministic timing margins across all four outputs, enabling reliable pattern edge alignment. |
Use Scenario: Storing current state bits in a 16-state traffic light controller with fault recovery via hardware reset. IC Role / Device Role / Timing Role: State register updated on each CLK cycle; asynchronous CLR forces safe "all-red" state on power loss or watchdog timeout. Use Value: –55°C to 125°C rating and ±2kV HBM support uninterrupted operation in outdoor junction boxes exposed to thermal cycling and ESD. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar D-type flip-flop register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AC175N | Same logic function and pinout, but PDIP-16 package (not SOIC); higher RθJA (120°C/W vs. 106.6°C/W) | Limited to through-hole prototyping or legacy board rework; unsuitable for surface-mount volume production | Select SN74AC175N only for hand-soldered evaluation or repair where SOIC footprint is unavailable. |
| 74LVC175PW | Lower VCC range (1.65V–3.6V); 24mA drive but only guaranteed to 3.6V; no 5V tolerance | Not usable in 5V systems or mixed-voltage designs requiring 5V-tolerant inputs; optimized for 3.3V-only portable gear | Choose 74LVC175PW only for battery-powered 3.3V applications where 1.65V minimum supply enables longer runtime. |
Compared with SN74AC175N and 74LVC175PW, CD74AC175M96E4 uniquely supports full 1.5V–5.5V operation in SOIC-16, delivering broader system compatibility, superior thermal performance, and guaranteed 5V interoperability without level shifters.

FAQ
What is the maximum clock frequency supported by CD74AC175M96E4 at 3.3V operation?
The CD74AC175M96E4 supports a maximum clock frequency of 81 MHz at VCC = 3.3V ± 0.3V over the –40°C to +85°C temperature range, as specified in Section 5.7 of the TI datasheet. This value reflects guaranteed timing performance under standard load conditions (CL = 50 pF) and accounts for process, voltage, and temperature variation.
Does CD74AC175M96E4 support 5V logic systems?
Yes, CD74AC175M96E4 fully supports 5V operation with VCC rated from 1.5V to 5.5V. At 5V, it delivers 114 MHz maximum clock frequency, 3.1 ns typical propagation delay, and maintains ±24mA output drive - making it compatible with legacy 5V TTL and CMOS systems without level translation.
How does the asynchronous clear (CLR) function behave in CD74AC175M96E4?
In CD74AC175M96E4, the active-low CLR input forces all Q outputs low immediately, independent of the clock signal or data inputs. This asynchronous reset occurs within 12.2 ns (max) at 5V, ensuring deterministic initialization for safety-critical or startup-sequence applications.
What package type and dimensions does CD74AC175M96E4 use?
CD74AC175M96E4 uses a 16-pin SOIC (D) package with nominal body dimensions of 9.9 mm × 3.9 mm and overall package size of 9.9 mm × 6.0 mm. It features NIPDAU lead finish, RoHS compliance, and JEDEC MSL Level-1 rating for unlimited floor life at ≤30°C/60% RH.
Is CD74AC175M96E4 suitable for automotive under-hood applications?
Yes, CD74AC175M96E4 is qualified for operation from –55°C to +125°C and exceeds ±2000V HBM ESD protection per MIL-STD-883. These specifications meet AEC-Q100 stress test requirements for non-automotive-grade components used in engine control modules, lighting controllers, and other under-hood subsystems.
