Product details
Overview
CD74HCT74M96G4 from Texas Instruments is a dual D-type positive-edge-triggered flip-flop with independent asynchronous clear and preset inputs per channel, operating from 4.5 V to 5.5 V, supporting –55°C to +125°C temperature range, delivering 25 MHz maximum clock frequency at 4.5 V, and driving up to 10 LSTTL loads in industrial control logic and clock division circuits.
For engineers reviewing the CD74HCT74M96G4 datasheet, CD74HCT74M96G4 pinout, CD74HCT74M96G4 application, or CD74HCT74M96G4 equivalent, key selection criteria include guaranteed positive-edge triggering behavior, TTL- and CMOS-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2 V), low quiescent current (ICC ≤ 80 µA), buffered inputs, and SOIC-14 packaging for space-constrained PCB layouts.
Technical Context
This device implements two fully independent D-type flip-flops, each with dedicated asynchronous active-low clear (CLR) and preset (PRE) inputs, enabling deterministic state initialization without clock dependency. Each channel responds only on the rising edge of its respective CLK signal, with setup time (tsu) of 12–18 ns and hold time (th) of 3 ns over full temperature range.
Input structure combines TTL-compatible voltage thresholds with CMOS-level leakage (II ≤ ±1 µA), while output stage uses balanced push-pull drivers capable of sourcing/sinking 4 mA while maintaining VOL ≤ 0.4 V and VOH ≥ 3.7 V at VCC = 4.5 V - ensuring robust interfacing with both legacy LSTTL and modern CMOS loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V logic rails and tolerance against supply ripple. |
| Operating Temperature | –55°C to +125°C - supports deployment in automotive under-hood, aerospace, and industrial environments. |
| Max Clock Frequency | 25 MHz at 4.5 V - defines highest reliable toggle rate for clock division or data sampling applications. |
| Input Thresholds | VIL(max) = 0.8 V, VIH(min) = 2 V - guarantees interoperability with 5 V TTL outputs and microcontroller GPIOs. |
| Propagation Delay | 35–53 ns (CLK→Q, CL = 50 pF) - determines minimum achievable timing margin in synchronous logic chains. |
| Quiescent Current | ICC ≤ 80 µA at TA = –55°C to +125°C - enables low-power operation in always-on monitoring subsystems. |
| Output Drive | ±4 mA - sufficient to directly drive 10 LSTTL loads or interface with high-impedance CMOS inputs without buffering. |
Pinout & Package
CD74HCT74M96G4 is housed in a 14-pin SOIC (D) package measuring 8.70 mm × 3.90 mm, with gull-wing leads, RoHS-compliant NiPdAu/Sn lead finish, and moisture sensitivity level (MSL) 1 (unlimited floor life at ≤30°C/60% RH).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | Channel 1 & 2 Clear (Active Low) | Asynchronous reset: forces Q = LOW regardless of clock or data state; requires pull-up for default inactive state. |
| 2, 12 | Channel 1 & 2 Data Input | Determines next-state Q value on subsequent positive clock edge; must be stable during tsu/th window. |
| 3, 11 | Channel 1 & 2 Clock Input | Rising-edge sensitive trigger; internal Schmitt-triggering not present - external debouncing required for switch inputs. |
| 4, 10 | Channel 1 & 2 Preset (Active Low) | Asynchronous set: forces Q = HIGH regardless of clock or data state; used for power-on initialization. |
| 5, 9 | Channel 1 & 2 True Output | Non-inverted registered output; fanout-limited by capacitive load (≤70 pF recommended). |
| 6, 8 | Channel 1 & 2 Complement Output | Inverted Q output; enables toggle configuration when connected to D input. |
| 7 | GND | Reference ground plane connection; must be low-impedance and adjacent to decoupling capacitor. |
| 14 | VCC | +5 V supply rail; requires 0.1 µF ceramic bypass capacitor placed within 2 mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent flip-flops | Enables compact implementation of two separate synchronous storage elements without cross-talk or shared timing constraints. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT74DR | Same SOIC-14 package, identical electrical specs, TI's newer production variant with updated MSL rating (Level-1 vs Level-1-260C-UNLIM). | No functional difference; suitable for new designs where latest qualification and traceability are required. | Select SN74HCT74DR for green-field designs needing current TI manufacturing standards and extended reflow compatibility. |
| MC74HCT74ADTR2G | SOIC-14, same VCC range and logic function, but ON Semiconductor part with slightly higher max ICC (100 µA) and different thermal metrics (RθJA = 100°C/W). | Acceptable for non-thermal-critical applications; may require layout review if operating near 125°C ambient. | Choose MC74HCT74ADTR2G only when dual-sourcing is mandated and thermal headroom exceeds 15°C. |
Compared with SN74HCT74DR, CD74HCT74M96G4 offers identical core functionality but reflects earlier TI production revision with legacy marking (HCT74M); versus MC74HCT74ADTR2G, it delivers lower thermal resistance and tighter ICC specification - making it preferable for thermally constrained or ultra-low-power industrial nodes.

FAQ
What is the maximum clock frequency supported by CD74HCT74M96G4?
The CD74HCT74M96G4 supports a maximum clock frequency of 25 MHz at VCC = 4.5 V and TA = –55°C to +125°C. This value decreases to 20 MHz at –40°C to +85°C and 16 MHz across the full –55°C to +125°C range, as specified in Section 6.5 of the TI SCHS409 datasheet. These limits ensure reliable setup/hold timing compliance under worst-case voltage and temperature conditions. The CD74HCT74M96G4 must not be operated beyond these frequencies without verifying timing margins via board-level validation.
Does CD74HCT74M96G4 require external pull-up resistors on PRE and CLR pins?
Yes, CD74HCT74M96G4 requires external pull-up resistors on both PRE and CLR pins to maintain inactive (HIGH) state during normal operation. Since these inputs are active-low and internally unconnected, floating pins risk unintended resets or presets due to noise coupling. A 10-kΩ resistor to VCC is recommended per TI application guidance (Section 9.2.1.2), ensuring stable logic levels while limiting leakage current to <0.5 µA. The CD74HCT74M96G4 datasheet explicitly states unused inputs must be terminated - leaving PRE or CLR floating violates recommended practice.
Can CD74HCT74M96G4 drive a 50-pF capacitive load reliably?
Yes, CD74HCT74M96G4 is characterized for reliable operation with a 50-pF capacitive load, as confirmed by switching characteristics in Section 6.6 of the TI SCHS409 datasheet. Propagation delay (tpd) and transition time (tt) parameters are explicitly tested under CL = 50 pF conditions. While the device can tolerate up to ~70 pF per TI design recommendations (Section 9.2.2), exceeding 50 pF increases propagation delay variance and may degrade edge fidelity. For optimal performance with the CD74HCT74M96G4, keep trace lengths short and avoid stubs or unterminated nets.
What is the purpose of the Q̅ output on CD74HCT74M96G4?
The Q̅ (complement) output on CD74HCT74M96G4 provides the logical inverse of the true Q output, enabling direct implementation of toggle functionality by connecting Q̅ to the D input. This configuration causes the flip-flop to change state on every active clock edge - a fundamental building block for divide-by-2 counters, switch debouncing, and state machines. The CD74HCT74M96G4's Q̅ output has matched drive strength and timing to Q, ensuring symmetrical behavior critical for reliable toggling. Its presence eliminates need for external inverters in many clock and control applications.
Is CD74HCT74M96G4 compatible with 3.3 V logic systems?
No, CD74HCT74M96G4 is not compatible with 3.3 V logic systems as a powered device. It requires a 4.5 V to 5.5 V supply (Section 6.2) and its input thresholds (VIH ≥ 2 V, VIL ≤ 0.8 V) are optimized for 5 V operation. While it may accept 3.3 V signals as inputs under certain conditions, doing so violates recommended operating conditions and risks unreliable recognition of logic HIGH states. For 3.3 V systems, use TI's SN74LVC74A or equivalent LVC-family device. The CD74HCT74M96G4 must be used exclusively in 5 V domains.
