Product details
Overview
74HC253N,652 from Nexperia is a dual 4-input CMOS multiplexer with independent 3-state outputs, 2.0–6.0 V supply range, and -40 °C to +125 °C operation. It routes one of four binary inputs per channel (1I0–1I3 or 2I0–2I3) to its respective output (1Y or 2Y) using shared S0/S1 select lines and individual nOE control-used in digital bus arbitration and signal routing in industrial control logic.
For engineers reviewing the 74HC253N,652 datasheet, 74HC253N,652 pinout, 74HC253N,652 application, or 74HC253N,652 equivalent, key selection criteria include its non-inverting data path, TTL-compatible input thresholds (for 74HCT variant), high noise immunity (>2000 V HBM ESD), and SO16 package compatibility with legacy 74-series layouts.
Technical Context
This device implements two independent 4:1 multiplexers sharing select inputs S0 and S1 but featuring separate output enable pins (1OE, 2OE) for precise channel gating. Each multiplexer supports high-impedance tri-state outputs, enabling direct connection to shared data buses without external buffering.
Input clamping diodes allow safe interfacing with voltages exceeding VCC when current-limiting resistors are used. The logic is fully static CMOS, with latch-up immunity exceeding 100 mA per JESD78 Class II Level B and compliance with JEDEC JESD8C (2.7–3.6 V) and JESD7A (2.0–6.0 V) standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.0 V to 6.0 V - supports mixed-voltage system integration and battery-powered designs down to 2 V. |
| Propagation delay (VCC = 4.5 V) | 20 ns max - enables reliable operation in 25 MHz digital control paths with timing margin. |
| Output drive (VCC = 4.5 V) | ±6.0 mA - sufficient to drive 10 LSTTL loads or 50 pF capacitive bus traces directly. |
| Input threshold (74HC) | VIL ≤ 0.5 V, VIH ≥ 3.15 V at VCC = 4.5 V - ensures robust noise margins in CMOS systems. |
| ESD rating (HBM) | ≥2000 V - meets industrial IEC 61000-4-2 level 2 requirements without external protection. |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives. |
| Power dissipation capacitance | 55 pF per multiplexer - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N). |
Pinout & Package
74HC253N,652 is supplied in the SO16 (SOT109-1) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm pitch, gull-wing leads. Pin 1 is marked by an index area; thermal pad is not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-LOW output enable - disables both outputs to high-impedance state independently. |
| 2, 14 | S1, S0 | Shared binary select inputs - determine which of four inputs (0–3) is routed to Y output. |
| 3–6, 10–13 | 1I0–1I3, 2I0–2I3 | Data inputs - two independent 4-bit source groups, each selectable to its own output. |
| 7, 9 | 1Y, 2Y | Non-inverting multiplexer outputs - deliver selected input with no polarity inversion. |
| 8 | GND | Ground reference - all voltage levels referenced to this node; must be low-impedance. |
| 16 | VCC | Positive supply - powers internal logic; decoupling capacitor required within 10 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Non-inverting data path | Preserves signal polarity across multiplexing - eliminates need for external inverters in feedback loops. |
| 3-state outputs | Enable direct bus connection without contention - supports multi-master arbitration in microcontroller peripheral interfaces. |
| Wide supply range (2.0–6.0 V) | Permits interoperability between 3.3 V logic and 5 V legacy systems without level shifters. |
| High noise immunity | CMOS input structure with >40 % VCC noise margin - resists EMI in motor drive and PLC environments. |
| Input clamp diodes | Allow safe interface to signals up to VCC + 0.5 V using series resistors - simplifies mixed-voltage sensor interfacing. |
Applications
| Industrial Control Logic | Digital Bus Arbitration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT253D,652 | TTL-compatible inputs (VIH = 2.0 V min); identical pinout and timing at 4.5–5.5 V. | Better suited for mixed 5 V TTL/CMOS systems where input drive strength from legacy logic is marginal. | Select when interfacing with 74LS or 74F series drivers without pull-ups. |
| SN74LV253APWR | Lower VCC range (1.65–5.5 V); higher drive (±12 mA); different pinout (TSSOP-16 only). | Preferred for ultra-low-voltage battery-powered IoT nodes requiring extended sleep-mode leakage performance. | Choose only if redesigning PCB layout for TSSOP and needing sub-2 V operation. |
Compared with 74HC253N,652, the 74HCT253D,652 offers guaranteed TTL-level input compatibility at 5 V but sacrifices 2 V minimum supply capability; the SN74LV253APWR provides lower voltage operation and stronger drive but requires board rework due to non-SO16 packaging and pin mismatch.

FAQ
What is the maximum operating frequency supported by the 74HC253N,652?
The 74HC253N,652 does not specify a maximum clock frequency, but its propagation delay is 20 ns typical at VCC = 4.5 V. This supports reliable operation in digital systems with signal periods ≥40 ns (i.e., ≤25 MHz toggle rate), assuming proper load capacitance (≤50 pF) and clean power supply decoupling. System-level timing must account for worst-case 53 ns delay at 125 °C.
Does the 74HC253N,652 support 3.3 V logic levels?
Yes, the 74HC253N,652 operates from 2.0 V to 6.0 V and is fully specified at 3.3 V. Its input thresholds scale with VCC: VIH ≥ 2.1 V and VIL ≤ 1.35 V at VCC = 3.3 V, providing >0.7 V noise margin-compatible with standard 3.3 V CMOS outputs and inputs without level translation.
Can the 74HC253N,652 replace the 74LS253 in existing designs?
No direct replacement: the 74HC253N,652 has CMOS input thresholds (VIH ≈ 70 % VCC), while 74LS253 requires TTL thresholds (VIH = 2.0 V). At 5 V, 74HC253N,652 accepts 74LS outputs, but 74LS inputs may not reliably recognize 74HC253N,652 outputs. Use 74HCT253D,652 instead for guaranteed TTL compatibility.
What is the function of the clamp diodes in the 74HC253N,652?
The 74HC253N,652 includes input clamp diodes to safely handle input voltages exceeding VCC or falling below GND. When used with appropriate series current-limiting resistors, these diodes allow interfacing with signals up to VCC + 0.5 V or down to −0.5 V-enabling robust sensor or mixed-voltage signal conditioning without external protection circuitry.
Is the 74HC253N,652 pin-compatible with other 74-series dual 4:1 multiplexers?
Yes, the 74HC253N,652 uses the standard SO16 pinout defined for 74xx253 devices (SOT109-1), matching 74HCT253D, 74AC253, and legacy 74LS253 in pin assignment. This allows drop-in substitution in existing PCB layouts when supply voltage and input logic family compatibility are verified.
