Product details
Overview
74HC151N,652 from NXP Semiconductors is an 8-input CMOS multiplexer with complementary outputs (Y and Y), three binary select inputs (S0–S2), and active-low enable input (E). It operates across −40 °C to +125 °C, supports 2.0–6.0 V supply, delivers propagation delay as low as 15 ns at VCC = 6.0 V, and features input clamp diodes for overvoltage interface protection. It is used in digital logic routing, data selection, and address decoding in industrial control systems.
For engineers reviewing the 74HC151N,652 datasheet, 74HC151N,652 pinout, 74HC151N,652 application, or 74HC151N,652 equivalent, key selection considerations include its CMOS-level input compatibility, dual complementary outputs, −40 °C to +125 °C temperature rating, DIP16 package form factor, and verified 8-channel data routing capability under 6 V operation.
Technical Context
The 74HC151N,652 implements a standard 8:1 multiplexer function using static CMOS logic, with non-inverting data path and active-low enable control. Its select inputs determine which of eight data inputs (I0–I7) appears at output Y, while Y provides the logical complement - enabling direct connection to both true and inverted logic paths without external inverters.
It complies with JEDEC standard no. 7A and integrates input clamp diodes that allow safe interfacing to signals exceeding VCC when used with current-limiting resistors. ESD protection exceeds 2000 V HBM and 200 V MM, supporting robust operation in industrial environments with moderate electrostatic risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | High-speed CMOS (74HC), TTL-compatible input thresholds not applicable |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct use with 3.3 V and 5 V logic domains |
| Propagation Delay (In → Y) | 15 ns typical at VCC = 6.0 V - supports >20 MHz switching in critical timing paths |
| Output Drive Capability | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74HC-series inputs or small capacitive loads |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and under-hood applications |
| Input Clamp Diodes | Integrated - permits safe interface to voltages up to VCC + 0.5 V with external current limiting |
| ESD Protection | HBM >2000 V, MM >200 V - reduces need for external ESD protection in board-level design |
Pinout & Package
74HC151N,652 is supplied in a plastic dual in-line package (DIP16), 300-mil body width, with through-hole mounting and 0.1-inch lead pitch. Pin 1 is located at the left end of the top row when viewed with notch or dot oriented upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| I0–I7 | Data inputs | Eight independent binary inputs routed selectively to Y/Y based on S0–S2 state |
| S0, S1, S2 | Select inputs | 3-bit binary code selects one of eight data inputs; S0 = LSB |
| E | Enable input (active LOW) | When HIGH, forces Y = LOW and Y = HIGH - disables data routing |
| Y | True output | Non-inverted selected input signal; drives downstream logic directly |
| Y | Complementary output | Inverted version of selected input - eliminates need for external inverter |
| VCC | Positive supply | 2.0–6.0 V power rail; decoupling capacitor required near pin 16 |
| GND | Ground reference | 0 V return path; must be low-impedance and tied to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Complementary outputs (Y and Y) | Eliminates need for external inverters in differential or dual-rail logic paths |
| Input clamp diodes | Enables safe level-shifting from higher-voltage sources using simple series resistors |
| JEDEC 7A compliance | Ensures interoperability with legacy 74-series logic families and standardized test protocols |
| Low quiescent current | ICC ≤ 160 μA max at 125 °C - minimizes standby power in battery-backed systems |
| Wide temperature range | Rated from −40 °C to +125 °C - suitable for uncontrolled industrial enclosures and motor drive cabinets |

FAQ
What is the maximum supply voltage rating for the 74HC151N,652?
The 74HC151N,652 has an absolute maximum supply voltage (VCC) of +7.0 V, but its recommended operating range is 2.0 V to 6.0 V. Operating continuously above 6.0 V risks parametric degradation and reduced reliability. The 74HC151N,652 must be powered within this 2.0–6.0 V window to guarantee all AC and DC specifications per the NXP datasheet Rev. 5.
Does the 74HC151N,652 support 3.3 V logic systems?
Yes, the 74HC151N,652 fully supports 3.3 V operation: its recommended VCC range includes 3.3 V, input thresholds scale with VCC (VIH ≈ 0.7×VCC), and it delivers VOL ≤ 0.26 V and VOH ≥ 3.1 V at 3.3 V with 4 mA load. The 74HC151N,652 is commonly deployed in mixed-voltage systems interfacing 3.3 V microcontrollers to 5 V peripherals.
What is the function of the Y and Y outputs on the 74HC151N,652?
The Y output delivers the non-inverted value of the selected input (I0–I7), while Y provides the exact logical complement - both are actively driven, not open-drain. This dual-output architecture allows the 74HC151N,652 to feed true and inverted signals simultaneously to downstream logic (e.g., set/reset latches or differential receivers) without adding external inverters or propagation delay.
Can the 74HC151N,652 be used with input signals exceeding VCC?
Yes - the 74HC151N,652 includes integrated input clamp diodes. When an input voltage exceeds VCC by more than ~0.5 V, the diode conducts, allowing safe operation if a current-limiting resistor is placed in series. This feature enables level translation from higher-voltage sensors or legacy buses, provided the clamping current remains within ±20 mA per pin as specified in the 74HC151N,652 datasheet.
Is the 74HC151N,652 pin-compatible with the 74HCT151N,652?
Yes - the 74HC151N,652 and 74HCT151N,652 share identical pinout, package (DIP16), and core functionality. The only differences are input threshold levels (CMOS vs. TTL) and recommended VCC range (2.0–6.0 V vs. 4.5–5.5 V). No PCB changes are required when substituting between them, though system-level voltage compatibility must be verified before replacement.
