Product details
Overview
74ACT11074NE4 from Texas Instruments is a dual positive-edge-triggered D-type flip-flop with independent asynchronous clear (CLR) and preset (PRE) inputs, operating at 4.5–5.5 V supply, supporting up to 100 MHz clock frequency, with 5 ns minimum pulse width for PRE/CLR and CLK, and TTL-compatible inputs. It is used in synchronous logic control, state machine sequencing, and data latching in industrial control and legacy digital systems.
For engineers reviewing the 74ACT11074NE4 datasheet, 74ACT11074NE4 pinout, 74ACT11074NE4 application, or 74ACT11074NE4 equivalent, key selection criteria include its dual DFF architecture with asynchronous set/reset, guaranteed 100 MHz operation at 5 V, ±24 mA output drive, 4.5–5.5 V supply range, and compatibility with standard 14-pin PDIP (N) packaging.
Technical Context
This device implements two independent edge-triggered D-type latches using TI's EPIC 1-μm CMOS process, enabling high-speed switching with latch-up immunity of 500 mA at 125°C. Each flip-flop responds to the low-to-high transition of CLK while PRE and CLR override all other inputs asynchronously.
Input voltage thresholds are TTL-compatible (VIL ≤ 0.8 V, VIH ≥ 2 V), and outputs meet AC specifications across –40°C to +85°C. Propagation delays range from 1.5 ns (min) to 9.6 ns (max) for tPLH/tPHL on CLK→Q, and 1.5–12.5 ns for PRE/CLR→Q transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation in 5 V TTL/CMOS mixed-signal systems |
| Max Clock Frequency | 100 MHz - supports high-speed synchronous logic in control and timing applications |
| Output Drive | ±24 mA - sufficient to directly drive multiple TTL loads or small capacitive buses |
| Propagation Delay | 1.5–9.6 ns (CLK→Q) - enables precise timing alignment in pipeline and register-transfer logic |
| Setup/Hold Time | tsu = 4.5 ns, th = 0 ns - simplifies timing closure with minimal data-stability window before clock edge |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded and automation equipment |
| Input Compatibility | TTL-voltage compatible (VIH ≥ 2 V, VIL ≤ 0.8 V) - interoperable with legacy 74LS/TTL logic families |
Pinout & Package
74ACT11074NE4 is supplied in a 14-pin plastic dual in-line package (PDIP-N), 300-mil width, with center-aligned VCC (pin 14) and GND (pin 7) to reduce high-speed switching noise.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1PRE, 2PRE | Asynchronous preset input | Active-low; forces Q = H regardless of CLK/D when asserted |
| 1CLR, 2CLR | Asynchronous clear input | Active-low; forces Q = L regardless of CLK/D when asserted |
| 1D, 2D | Data input | Samples on rising CLK edge if PRE/CLR inactive (high) |
| 1CLK, 2CLK | Clock input | Positive-edge triggered; level-sensitive threshold, not rise-time dependent |
| 1Q, 2Q | True output | Complements 1Q/2Q; latched value after CLK↑ with valid setup |
| 1Q, 2Q | Inverted output | Complementary to true output; supports differential signaling or feedback paths |
| VCC (pin 14) | Power supply | Center-pin placement minimizes ground bounce and supply noise coupling |
| GND (pin 7) | Ground reference | Center-pin placement provides symmetrical return path for both flip-flops |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent D-type flip-flops | Enables compact implementation of 2-bit registers or parallel loadable counters without external gating |
| Asynchronous PRE/CLR per channel | Allows immediate initialization or reset of individual flip-flops without waiting for clock edge |
| EPIC 1-μm CMOS process | Delivers high speed with low power consumption and robust latch-up immunity (500 mA @ 125°C) |
| TTL-compatible input thresholds | Eliminates need for level-shifting when interfacing with legacy 74LS, 74F, or microcontroller GPIOs |
| Center-pin VCC/GND configuration | Reduces simultaneous switching noise and improves signal integrity in dense PCB layouts |
Applications
| Industrial PLC I/O Register | Legacy Bus Interface Latch |
|---|---|
Use Scenario: Capturing sensor status or actuator command signals synchronized to a system clock in programmable logic controllers.

IC Role / Device Role / Timing Role: Serves as a hardened, temperature-rated storage element for critical go/no-go decision flags. Use Value: –40°C to +85°C rating ensures reliability in factory-floor thermal environments; 500 mA latch-up immunity prevents failure under ESD or transient stress. |
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 |
|---|---|---|---|
| SN74ACT112N | J-K flip-flop topology instead of D-type; identical 14-pin PDIP package and AC specs | Requires external gating for D-equivalent behavior; less direct for data capture applications | Choose only if J-K functionality (toggle/set/reset) is required over pure D-latch behavior |
| 74ACT74N | Same dual DFF function but lacks individual PRE/CLR per flip-flop (shared reset only) | Cannot independently preset/clear one stage without affecting the other | Select 74ACT11074NE4 when per-channel asynchronous control is mandatory for fault isolation or multi-mode operation |
Compared with SN74ACT112N and 74ACT74N, the 74ACT11074NE4 uniquely provides fully independent preset and clear per flip-flop in a 14-pin PDIP, enabling asymmetric initialization and higher functional density in safety-critical or modular control logic.

FAQ
What is the maximum clock frequency supported by the 74ACT11074NE4?
The 74ACT11074NE4 is characterized for operation up to 100 MHz across the full temperature range (–40°C to +85°C) at VCC = 4.5–5.5 V. This maximum frequency is verified under recommended operating conditions with CL = 50 pF and specified input transition rates. The 74ACT11074NE4 achieves this performance using TI's EPIC 1-μm CMOS process and center-pin power/ground layout to minimize switching noise.
Does the 74ACT11074NE4 support TTL-level input signals?
Yes, the 74ACT11074NE4 features TTL-voltage compatible inputs with VIH ≥ 2.0 V and VIL ≤ 0.8 V, allowing direct interfacing with 74LS, 74F, and other legacy TTL families without level-shifting circuitry. This compatibility is maintained across the full operating temperature range and supply voltage (4.5–5.5 V). The 74ACT11074NE4 leverages this feature to simplify integration into mixed-logic systems.
What package type is used for the 74ACT11074NE4?
The 74ACT11074NE4 uses a 14-pin plastic dual in-line package (PDIP-N), 300-mil width, with standard through-hole mounting. Its pinout follows JEDEC MS-001, featuring center-aligned VCC (pin 14) and GND (pin 7) to reduce high-speed switching noise. This package is RoHS-compliant and rated for industrial temperature operation (–40°C to +85°C). The 74ACT11074NE4 part marking appears as "74ACT11074N" on the top surface.
How does the asynchronous preset and clear function in the 74ACT11074NE4?
In the 74ACT11074NE4, each flip-flop has dedicated active-low PRE and CLR inputs that override the clock and data inputs: asserting 1PRE forces 1Q = H and 1Q = L immediately; asserting 1CLR forces 1Q = L and 1Q = H. These functions operate independently per channel and take effect regardless of CLK or D state. The 74ACT11074NE4 guarantees 5 ns minimum pulse width for reliable assertion of these controls.
Is the 74ACT11074NE4 suitable for industrial temperature environments?
Yes, the 74ACT11074NE4 is fully characterized and qualified for operation from –40°C to +85°C, meeting industrial-grade environmental requirements. Its EPIC 1-μm CMOS process delivers 500 mA typical latch-up immunity at 125°C, and its electrical specifications-including propagation delay, setup time, and output drive-are guaranteed across this full range. The 74ACT11074NE4 is widely deployed in PLCs, motor drives, and factory-floor test equipment where thermal resilience is critical.
