Product details
Overview
CD74HCT175M96 from Texas Instruments is a high-speed CMOS quad D-type flip-flop with asynchronous master reset, positive-edge clock triggering, complementary Q/Q̅ outputs per stage, and LSTTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V). It operates from 4.5 V to 5.5 V, delivers 10 LSTTL load drive capability, and supports industrial/military temperature range (–55 °C to +125 °C) in a 16-pin SOIC package - used in synchronous data latching, state register storage, and clock-domain synchronization circuits.
For engineers reviewing the CD74HCT175M96 datasheet, CD74HCT175M96 pinout, CD74HCT175M96 application, or CD74HCT175M96 equivalent, key selection criteria include guaranteed LSTTL input compatibility, common-clock/common-reset architecture across four independent flip-flops, propagation delay ≤ 50 ns (CL = 50 pF, VCC = 4.5 V), and tape-and-reel packaging for automated assembly.
Technical Context
The CD74HCT175M96 implements four edge-triggered D-type flip-flops sharing one clock (CP) and one active-low asynchronous master reset (MR) input. Each stage transfers Dn to Qn on the rising edge of CP while simultaneously asserting Q̅n as the logical inverse - no internal feedback or preset functionality is present.
All timing parameters are specified under controlled conditions: input rise/fall time ≤ 6 ns, CL = 50 pF, and operating voltage 4.5 V to 5.5 V. Setup time (tSU) is 25 ns min, hold time (tH) is 5 ns min, and maximum clock frequency is 20 MHz over –55 °C to +125 °C.

| 9 (Q3) | Stage 3 true output | Final stage output; identical electrical specs to Q0–Q2 - usable as end-of-register indicator |
| 10 (Q̅3) | Stage 3 complement output | Supports full 4-bit bidirectional data flow when paired with external transceivers |
| 11 (D3) | Stage 3 data input | Accepts serial or parallel data; timing aligned to shared CP/MR signals |
| 12 (D2) | Stage 2 data input | Mid-register input; critical for pipeline stages requiring staggered enable timing |
| 13 (Q2) | Stage 2 true output | Intermediate register output; feeds next-stage logic or status monitoring circuitry |
| 14 (Q̅2) | Stage 2 complement output | Used in XOR-based parity generation or error-detection logic trees |
| 15 (CP) | Clock input (positive edge) | Edge-sensitive trigger for all four flip-flops; requires clean, monotonic transition to avoid metastability |
| 16 (VCC) | Positive supply | 4.5–5.5 V DC source; bypassing with 0.1 µF ceramic capacitor near pin essential for noise immunity |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT175N | Same HCT logic family, identical pinout and AC/DC specs, but in PDIP-16 package (not tape-and-reel) | Suitable for prototyping or low-volume through-hole assembly; lacks SOIC thermal performance and automated placement compatibility | Select SN74HCT175N only when manual soldering or breadboarding is required - CD74HCT175M96 is preferred for production SMT lines. |
| CD74HC175M96 | Same package and pinout, but HC family: 2–6 V operation, higher noise immunity (30% VCC), no LSTTL input compatibility | Applicable where mixed-voltage systems exist or where strict TTL interoperability is unnecessary | Choose CD74HC175M96 if supply voltage may drop below 4.5 V or if interfacing exclusively with CMOS logic - CD74HCT175M96 remains optimal for 5 V TTL ecosystems. |
Compared with SN74HCT175N and CD74HC175M96, CD74HCT175M96 uniquely combines LSTTL input compatibility, SOIC-16 tape-and-reel packaging, and extended temperature qualification - making it the default choice for high-reliability 5 V digital systems requiring automated manufacturing.

FAQ
What is the maximum clock frequency supported by CD74HCT175M96 over its full temperature range?
The CD74HCT175M96 supports a maximum clock frequency of 16 MHz across the full –55 °C to +125 °C operating range, as specified in the switching characteristics table. At 25 °C and VCC = 4.5 V, the device achieves up to 25 MHz, but design margins require derating for worst-case thermal and voltage conditions. This makes CD74HCT175M96 suitable for deterministic real-time control loops running below 16 MHz.
Does CD74HCT175M96 require external pull-up or pull-down resistors on its MR or CP inputs?
No, CD74HCT175M96 does not require external biasing on MR or CP inputs. Its CMOS input structure exhibits ≤1 µA leakage current, and the MR pin has an internal passive pull-up when unused (per TI application guidance), while CP is edge-triggered and tolerant of floating states only during power-up. However, best practice dictates tying MR to VCC via a 10 kΩ resistor in normal operation to prevent spurious resets - a requirement explicitly noted in TI's HCT logic design guidelines for CD74HCT175M96.
Can CD74HCT175M96 drive a 50 pF capacitive load at 20 MHz without signal degradation?
Yes, CD74HCT175M96 is characterized for CL = 50 pF in its switching specifications, with propagation delay ≤ 50 ns and output transition times ≤ 22 ns at VCC = 4.5 V and 25 °C. While 20 MHz operation falls within its 25 MHz typical fMAX, sustained 20 MHz toggling into 50 pF requires proper PCB layout: short traces, ground plane adjacency, and local 0.1 µF decoupling at VCC. These conditions ensure CD74HCT175M96 maintains signal integrity without overshoot or excessive rise/fall distortion.
Is CD74HCT175M96 pin-compatible with the obsolete CD74HCT175M variant?
Yes, CD74HCT175M96 is pin-compatible with the obsolete CD74HCT175M - both use identical 16-pin SOIC (D) packages with matching pin assignments, thermal pad layout, and mechanical footprint. The "96" suffix denotes tape-and-reel packaging (2500 units per reel), whereas "M" indicated tube packaging. Electrical and timing specifications are identical; only packaging and ordering logistics differ. Customers upgrading from CD74HCT175M to CD74HCT175M96 require no PCB redesign.
What is the absolute maximum supply voltage rating for CD74HCT175M96, and what happens if exceeded?
The absolute maximum DC supply voltage for CD74HCT175M96 is 7 V, as stated in the Absolute Maximum Ratings table. Exceeding this limit - even momentarily - risks permanent damage to the internal gate oxides due to dielectric breakdown. TI explicitly cautions that operation above 7 V is not implied and may cause irreversible failure. For robust designs, CD74HCT175M96 should be powered within its recommended 4.5–5.5 V range, with transient suppression (e.g., TVS diode) if upstream regulators lack tight tolerance.
