Product details
Overview
74HC151P-E from Renesas is a high-speed 1-of-8-line data selector/multiplexer in a 16-pin DIP package, operating from 2 V to 6 V with propagation delay of 18 ns (typ, CL = 50 pF) and dual true (Y) and complement (W) outputs. It enables selection of one of eight digital inputs (D0–D7) via three address lines (A, B, C) under active-low strobe control, used in address decoding and signal routing in digital logic systems.
For engineers reviewing the 74HC151P-E datasheet, 74HC151P-E pinout, 74HC151P-E application, or 74HC151P-E equivalent, key selection criteria include its dual-output architecture, wide supply voltage range, low quiescent current (4 µA max), and compatibility with LSTTL loads - critical for legacy TTL-to-CMOS interface design and combinatorial logic consolidation.
Technical Context
The 74HC151P-E implements standard CMOS logic with a 3-bit binary address decoder driving an 8-to-1 analog/digital multiplexer core. Its strobe-enabled operation ensures output disable (Y = L, W = H) when S is high, preventing bus contention during deselection.
It supports rail-to-rail input switching (VIH ≥ 3.15 V at VCC = 4.5 V; VIL ≤ 1.35 V), delivers ±25 mA output drive capability, and maintains stable timing across –40°C to +85°C with propagation delays specified per path: Dn→Y/W, A/B/C→Y/W, and S→Y/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered logic |
| Propagation Delay | 18 ns typ (Dn→Y/W, CL = 50 pF, VCC = 4.5 V) - enables reliable operation up to ~25 MHz clocked control |
| Output Drive | ±25 mA - sufficient to directly drive LEDs or fan out to 10 LSTTL loads without buffers |
| Quiescent Current | 4 µA max (Ta = 25°C) - suitable for low-power standby states in portable logic |
| Input Thresholds | VIH = 3.15 V min, VIL = 1.35 V max (VCC = 4.5 V) - ensures noise margin >0.8 V in 5 V systems |
| Operating Temp | –40°C to +85°C - qualified for industrial-grade embedded control environments |

| 11 | B | Address bit 1 - middle bit of 3-bit select code |
| 12 | C | Address bit 2 - MSB of 3-bit select code |
| 13 | Strobe S | Enable control - device enabled only when S = L; forces Y=L, W=H when S=H |
| 14 | Y | True output - active-high replica of selected Dn when enabled |
| 15 | W | Inverted output - active-low complement of selected Dn when enabled |
| 16 | VCC | Positive supply - powers all internal CMOS circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Dual complementary outputs | Simultaneous Y (true) and W (inverted) outputs eliminate need for external inverters in differential routing |
| Wide supply voltage range | 2 V to 6 V operation allows direct interface with 3.3 V microcontrollers and legacy 5 V logic without level shifters |
| Low static power consumption | 4 µA max ICC enables use in always-on monitoring circuits without significant battery drain |
| High noise immunity | Guaranteed VIH/VIL margins (>0.8 V at 4.5 V) reduce susceptibility to ground bounce and crosstalk in dense PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 1-of-8 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC151N | Same logic function, identical pinout, TI-manufactured; tpd = 19 ns (typ), ICC = 8 µA max | Higher quiescent current; slightly slower propagation; same DIP-16 footprint | Preferred where TI's qualification and long-term availability are required |

FAQ
What is the maximum supply voltage rating for the 74HC151P-E?
The 74HC151P-E has an absolute maximum supply voltage (VCC) rating of +7.0 V, but its recommended operating range is 2.0 V to 6.0 V. Operation above 6.0 V risks exceeding safe operating limits and may cause irreversible damage. The 74HC151P-E is rated for continuous operation at 6.0 V with full specification compliance, including propagation delay and output drive strength.
Does the 74HC151P-E support 3.3 V logic systems?
Yes, the 74HC151P-E fully supports 3.3 V operation: its VIH minimum is 2.1 V (at VCC = 3.3 V, derived from proportional threshold specs), and VOL remains ≤ 0.1 V at IOL = 4 mA. Input thresholds scale with VCC, ensuring reliable recognition of 3.3 V logic levels without external level shifting - a key feature confirmed in the Recommended Operating Conditions table of the 74HC151P-E datasheet.
What happens to the outputs when the strobe input is high?
When the strobe input (S) is high, the 74HC151P-E disables its multiplexer function: the true output (Y) is forced low and the complement output (W) is forced high, regardless of address or data inputs. This behavior is explicitly defined in the Function Table and Logic Diagram of the 74HC151P-E datasheet and ensures predictable, contention-free bus states during deselection.
Is the 74HC151P-E pin-compatible with other 74HC151 variants like HD74HC151FPEL?
No - the 74HC151P-E uses a 16-pin DIP (PRDP0016AE-B) package, while HD74HC151FPEL uses a SOP-16 (PRSP0016DH-B) surface-mount package. Although both share identical logic functionality and pin numbering, their physical footprints, soldering requirements, and thermal profiles differ. The 74HC151P-E is not a drop-in replacement for SOP variants without PCB redesign.
What is the input capacitance of the 74HC151P-E?
The 74HC151P-E has a maximum input capacitance (Cin) of 10 pF, as specified in the Electrical Characteristics table of its datasheet. This value applies across all inputs (A, B, C, D0–D7, S) and is measured at VCC = 5 V with standard test conditions. Low Cin minimizes loading on driving sources and supports clean signal integrity in high-speed address/data paths.
