Product details
Overview
74HC157N,652 from NXP Semiconductors is a quad 2-input CMOS multiplexer with non-inverting outputs, pin-compatible with LSTTL, operating from 2.0 V to 6.0 V supply, featuring 10 ns propagation delay at 6.0 V and −40 °C to +125 °C temperature range. It implements four independent 2:1 data selections controlled by a common select (S) and active-low enable (E), used in register-to-bus data routing and combinational logic generation.
For engineers reviewing the 74HC157N,652 datasheet, 74HC157N,652 pinout, 74HC157N,652 application, or 74HC157N,652 equivalent, this device serves as a logic-level 4-pole, 2-position switch for digital signal path selection in industrial control, test equipment, and legacy TTL interface bridging - where low static current (<160 µA), ESD-hardened inputs (HBM >2 kV), and true-output behavior are critical.
Technical Context
The 74HC157N,652 implements four parallel 2:1 multiplexers sharing one data select (S) and one active-low enable (E). Each output (1Y–4Y) follows Y = E̅ × [(I1 × S) + (I0 × S̅)], enabling simultaneous selection of four bits from two 4-bit sources. Its CMOS silicon-gate architecture ensures rail-to-rail output swing and high noise immunity.
It operates across a wide voltage range (2.0–6.0 V) with input thresholds scaling with VCC for 74HC logic family compatibility. The device supports full industrial and extended temperature operation (−40 °C to +125 °C) and meets JEDEC Std 7A, making it suitable for robust embedded digital systems requiring deterministic timing and low-power static operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - Enables direct interfacing with 3.3 V and 5 V logic domains without level shifters. |
| Propagation Delay | 10 ns (typ) at VCC = 6.0 V - Supports synchronous data routing up to ~50 MHz in critical paths. |
| Output Drive | ±5.2 mA at VCC = 6.0 V - Drives standard 74HC loads and short PCB traces without buffering. |
| Input Thresholds | VIL ≤ 0.5 V, VIH ≥ 4.2 V at VCC = 6.0 V - Provides >1.8 V noise margin for clean switching in noisy environments. |
| Static Current | 160 µA max at +125 °C - Ensures low power consumption in always-on industrial monitoring circuits. |
| ESD Protection | HBM >2000 V, MM >200 V - Reduces risk of handling damage during manual assembly and rework. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive auxiliary modules and industrial motor drives. |
Pinout & Package
74HC157N,652 uses the plastic dual in-line package (DIP16), 300-mil body width, with through-hole mounting and 2.54 mm lead pitch. Pin 1 is marked by a notch or dot; pin 8 is GND and pin 16 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Common data select input | Selects source 0 (I0) when LOW or source 1 (I1) when HIGH for all four channels simultaneously. |
| 2,5,11,14 (1I0–4I0) | Data inputs, source 0 | Four independent LOW-true inputs from first 4-bit data group; tied to registers or bus segments. |
| 3,6,10,13 (1I1–4I1) | Data inputs, source 1 | Four independent LOW-true inputs from second 4-bit data group; enables dual-source arbitration. |
| 4,7,9,12 (1Y–4Y) | Multiplexer outputs | Non-inverting, actively driven outputs delivering selected I0/I1 bit with rail-to-rail swing. |
| 8 (GND) | Ground reference | Primary return path for all internal logic and output currents; must be low-impedance for noise control. |
| 15 (E) | Active-low enable | Forces all outputs LOW when HIGH; allows global disable for bus contention avoidance or power gating. |
| 16 (VCC) | Positive supply | Single 2.0–6.0 V supply powers all logic and output stages; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Quad 2:1 multiplexing | Four independent channels share one select and enable line - reduces control logic and PCB routing vs discrete muxes. |
| True (non-inverting) outputs | Eliminates need for external inverters in feedback or latch-based logic designs using 74HC157N,652 outputs. |
| Wide supply range (2.0–6.0 V) | Operates directly from 3.3 V microcontroller I/O rails or legacy 5 V systems - no external regulators needed. |
| JEDEC Std 7A compliance | Guarantees interoperability with industry-standard TTL and CMOS logic families in mixed-voltage systems. |
| −40 °C to +125 °C operation | Validated performance across full industrial temperature range - suitable for uncooled enclosures and motor drive cabinets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC158N,652 | Inverting outputs; identical pinout and electrical specs except output polarity. | Requires downstream inversion if true-logic behavior is mandatory; unsuitable where output polarity is fixed by system design. | Choose only if downstream logic expects inverted outputs or if inverting buffers are already present. |
| SN74LV157N | Lower VCC range (2.0–5.5 V); higher drive strength (±12 mA); LV logic thresholds (VIH = 1.7 V min at 3.3 V). | Better suited for 3.3 V-only systems with heavy capacitive loads; not drop-in for 6 V operation or 5 V TTL compatibility. | Select when designing new 3.3 V systems prioritizing drive capability over 5 V/6 V flexibility. |
Compared with 74HC157N,652, the 74HC158N,652 offers identical functionality with inverted outputs - requiring redesign of downstream logic - while SN74LV157N trades 6 V operation and TTL compatibility for enhanced 3.3 V drive and lower threshold margins, making it optimal for modern low-voltage digital subsystems.

FAQ
What is the maximum supply voltage rating for the 74HC157N,652?
The absolute maximum supply voltage for the 74HC157N,652 is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V. Operating continuously above 6.0 V risks exceeding internal oxide breakdown limits and may cause irreversible damage. For reliable long-term use, maintain VCC within the 2.0–6.0 V window specified in Table 5 of the NXP datasheet for 74HC157N,652.
Does the 74HC157N,652 support 3.3 V logic levels?
Yes, the 74HC157N,652 fully supports 3.3 V operation: its recommended VCC range includes 3.3 V, input thresholds scale with supply (VIH ≈ 0.7×VCC), and outputs swing rail-to-rail. At VCC = 3.3 V, VIH is ~2.3 V and VOL remains ≤0.1 V at 4 mA load - ensuring clean interfacing with standard 3.3 V microcontrollers and FPGAs when using the 74HC157N,652.
How does the enable (E) pin function on the 74HC157N,652?
The E pin on the 74HC157N,652 is an active-low enable: when E = HIGH, all four outputs (1Y–4Y) are forced LOW regardless of S or input states; when E = LOW, normal multiplexing resumes. This allows global output disable for bus isolation, power sequencing, or fault-safe shutdown - a key feature distinguishing the 74HC157N,652 from simpler 2:1 mux ICs lacking enable control.
Is the 74HC157N,652 pin-compatible with the 74HCT157N variant?
Yes, the 74HC157N,652 is pin-compatible with the 74HCT157N, sharing identical DIP16 pinout, pin functions, and package dimensions. The difference lies in input threshold compatibility: 74HCT157N accepts TTL-level inputs (VIH = 2.0 V min), while 74HC157N,652 requires CMOS-level thresholds (VIH ≈ 0.7×VCC). Swapping them requires verifying source logic family compatibility before substitution in existing 74HC157N,652 designs.
What is the typical propagation delay of the 74HC157N,652 at 5 V supply?
At VCC = 5.0 V and CL = 15 pF, the typical propagation delay (tpd) of the 74HC157N,652 is 11 ns for both data inputs (I0/I1) and select (S) to output (Y), as specified in Table 7 of the NXP datasheet. This value reflects tPLH/tPHL under standard test conditions and enables reliable operation in digital systems with clock periods ≥25 ns - confirming suitability for 40 MHz synchronous data routing when using the 74HC157N,652.
