Product details
Overview
CD74ACT151M96 from Texas Instruments is a high-speed 8-line to 1-line CMOS data selector/multiplexer with TTL-compatible inputs, ±24 mA output drive, and dual complementary outputs (Y and W). It operates across –40°C to +85°C at 4.5 V–5.5 V supply, enabling asynchronous data routing in digital control logic and Boolean function generation.
For engineers reviewing the CD74ACT151M96 datasheet, CD74ACT151M96 pinout, CD74ACT151M96 application, or CD74ACT151M96 equivalent, key selection criteria include its 8:1 multiplexing capability, strobe-controlled enable/disable behavior, balanced propagation delays, and compatibility with legacy TTL signal levels in mixed-logic systems.
Technical Context
The CD74ACT151M96 implements a single 8:1 multiplexer using silicon-gate CMOS technology with push-pull outputs. Its address inputs (A, B, C) select one of eight data sources (D0–D7), while the active-low strobe (G) forces Y = low and W = high regardless of address state.
It features TTL-voltage-compatible inputs (VIH = 2 V min, VIL = 0.8 V max), dual complementary outputs (Y = selected input, W = inverted Y), and SCR-latchup-resistant design. Propagation delays range from 3.0 ns (G→Y) to 21.6 ns (A/B/C→W) over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Function | 8-line to 1-line data selector/multiplexer with active-low strobe and complementary outputs |
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL/CMOS logic rails |
| Output Drive | ±24 mA - supports fanout to 15 F-series devices and drives moderate capacitive loads |
| Propagation Delay | 3.0 ns (min G→Y) to 21.6 ns (max A/B/C→W) - enables high-speed data routing in synchronous logic |
| Input Compatibility | TTL-voltage compatible (VIH ≥ 2 V, VIL ≤ 0.8 V) - interoperable with legacy 74LS/74F families without level shifters |
| ESD Protection | ±2000 V HBM - exceeds MIL-STD-883 requirement, suitable for industrial handling environments |
| Operating Temp | –40°C to +85°C - qualified for commercial and extended-temperature embedded applications |
Pinout & Package
CD74ACT151M96 is packaged in a 16-pin SOIC (D package), measuring 8.65 mm × 6 mm overall with a body size of 8.65 mm × 3.9 mm. The thermal pad is not present in this SOIC variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | D3 | Data input 3 - one of eight parallel data sources selectable via A/B/C address lines |
| 2 | D2 | Data input 2 - contributes to 8:1 selection matrix; must be terminated if unused |
| 3 | D1 | Data input 1 - TTL-compatible input; requires fast edge rates (≤10 ns/V) to prevent oscillation |
| 4 | D0 | Data input 0 - LSB of data bank; tied to VCC or GND if unused per CMOS best practice |
| 5 | Y | True output - reflects selected Dn value when G = low; high-impedance when G = high |
| 6 | W | Inverted output - logic complement of Y; driven high when G = high |
| 7 | G | Active-low strobe - disables multiplexer and forces Y = L / W = H when high |
| 8 | GND | Ground reference - return path for all I/O and supply currents; critical for noise immunity |
| 9 | C | MSB address select - forms 3-bit binary code (CBA) to decode D0–D7 selection |
| 10 | B | Mid-bit address select - determines which octant of data inputs is routed to Y/W |
| 11 | A | LSB address select - completes 3-bit address; transition timing affects worst-case tPHL/tPLH |
| 12 | D7 | Data input 7 - MSB of data bank; used in Boolean function generation and parallel-to-serial conversion |
| 13 | D6 | Data input 6 - supports multi-channel source selection in test equipment and data acquisition |
| 14 | D5 | Data input 5 - requires same termination as other inputs: VCC or GND, never floating |
| 15 | D4 | Data input 4 - complements D0–D3 to complete full 8-input set; shares same VIH/VIL thresholds |
| 16 | VCC | Positive supply - powers internal logic and output drivers; requires local 0.1 µF bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Complementary outputs (Y and W) | Eliminates need for external inverters in applications requiring both true and inverted data paths |
| TTL-compatible inputs | Enables direct interface with 74LS/74F logic without level-shifting circuitry or additional components |
| SCR-latchup-resistant process | Prevents destructive latch-up under transient overvoltage or ESD events in industrial power environments |
| Balanced propagation delays | Minimizes skew between address transitions and output response, critical for synchronous bus arbitration |
| ±24 mA output drive | Supports driving multiple downstream gates or moderate PCB trace capacitance (<50 pF) without buffering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT151N | Same logic function and pinout; identical AC/DC specs but offered in PDIP package instead of SOIC | Preferred for through-hole prototyping or legacy board rework where SOIC footprint is unavailable | Select SN74ACT151N when manual soldering or socket-based validation is required |
| CD74HC151M96 | Lower drive (±5.2 mA), higher propagation delay (max 32 ns), and reduced ESD rating (±2 kV HBM vs ±2 kV) | Suitable for low-power, non-critical routing where speed and robustness are secondary to quiescent current | Choose CD74HC151M96 only when supply current < 8 µA at 25°C is mandatory and 5.5 V operation is not needed |
Compared with SN74ACT151N, CD74ACT151M96 offers identical functionality in surface-mount form for automated assembly; compared with CD74HC151M96, it delivers 4.6× higher output drive and 30% faster switching at 5 V, making it preferable for noise-immune, high-fanout digital control paths.

FAQ
What is the maximum operating temperature range for CD74ACT151M96?
The CD74ACT151M96 is rated for operation from –40°C to +85°C under recommended conditions. This range is validated per TI's characterization and supports use in commercial and extended-temperature industrial environments. Operation outside this range may violate absolute maximum ratings and compromise reliability. Always refer to the Recommended Operating Conditions table in the official datasheet for voltage and timing derating guidance at temperature extremes.
Does CD74ACT151M96 support 3.3 V logic inputs?
No, CD74ACT151M96 does not reliably accept 3.3 V logic inputs as valid high-level signals. Its VIH(min) is specified at 2.0 V only when VCC = 4.5 V–5.5 V; at 3.3 V supply, the device is not characterized or guaranteed. For 3.3 V–5 V interfacing, a level translator or buffer such as SN74LVC1T45 is required upstream of CD74ACT151M96 inputs.
Can unused inputs on CD74ACT151M96 be left floating?
No, unused inputs on CD74ACT151M96 must never be left floating. All unused address (A/B/C) and data (D0–D7) inputs must be tied to either VCC or GND to prevent excessive current draw, oscillation, or increased power consumption. TI recommends 10 kΩ pull-up or pull-down resistors for inputs that may be dynamically disabled during operation.
What is the purpose of the W output on CD74ACT151M96?
The W output on CD74ACT151M96 provides the logical inverse of the Y output. When G = low and a data input Dn is selected, W = NOT(Dn). When G = high, W is forced high regardless of address or data states. This eliminates the need for an external inverter in designs requiring both true and complemented data paths, such as differential bus drivers or XOR-based parity generators.
Is CD74ACT151M96 pin-compatible with CD74HC151M96?
Yes, CD74ACT151M96 and CD74HC151M96 share identical 16-pin SOIC (M96) packaging and pinout, including matching VCC, GND, address, data, strobe, and Y/W terminal assignments. However, they differ electrically: CD74ACT151M96 offers higher drive (±24 mA vs ±5.2 mA), faster timing, and stricter input thresholds. Direct substitution requires verification of load, speed, and supply voltage requirements.
