Product details
Overview
74HC258P-E from Renesas Electronics is a quad 2-to-1-line data selector/multiplexer with 3-state outputs, designed for bus-oriented digital systems. It operates across 2–6 V supply, delivers 11 ns typical propagation delay (CL = 50 pF), supports ±35 mA output current, and features low quiescent ICC of 4 µA max at 25°C - enabling reliable signal routing in industrial control logic and legacy TTL-compatible interfaces.
For engineers reviewing the 74HC258P-E datasheet, 74HC258P-E pinout, 74HC258P-E application, or 74HC258P-E equivalent, key selection criteria include its 3-state output control architecture, DIP-16 package compatibility, wide VCC range, high fanout (15 LSTTL loads), and guaranteed operation from –40°C to +85°C in standard-grade applications.
Technical Context
The 74HC258P-E integrates four independent 2:1 multiplexers sharing a common select (S) input and a global 3-state output enable (G) control. Each channel routes either A or B input to Y based on S level while G independently places all Y outputs into high-impedance state when asserted high.
Its CMOS HC-series design ensures compatibility with both 5 V TTL and 3.3 V logic families, with VIH/VIL thresholds scaling proportionally to VCC (e.g., VIH = 4.2 V min at VCC = 6 V). Propagation delays are specified under controlled CL = 50 pF loading and input edge rates ≤ 6 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74HC - high-speed CMOS compatible with TTL input thresholds and drive strength |
| Supply Voltage Range | 2.0–6.0 V - supports mixed-voltage system interfacing without level shifters |
| Propagation Delay (tpd) | 11 ns typ (CL = 50 pF, VCC = 4.5 V) - enables sub-20 MHz clock domain operation |
| Output Drive | ±35 mA per output - sufficient to drive 15 LSTTL loads directly |
| Quiescent Supply Current | 4 µA max at 25°C - suitable for low-power standby modes in battery-backed logic |
| Operating Temperature | –40°C to +85°C - qualified for industrial ambient environments |
| 3-State Enable Polarity | Active-High G input - simplifies bus arbitration control with standard logic levels |
Pinout & Package
Dual In-line Package (DIP-16), 7.62 mm pitch, 19.2 mm × 6.3 mm body, through-hole mounting. Pin 1 marked by notch or dot; pin 8 = GND, pin 16 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Select Input | Common control for all four multiplexers: selects A (low) or B (high) path |
| 2–5 (1A–4A) | Data Input A | First input set for each of four channels; routed to Y when S = L |
| 6–9 (1B–4B) | Data Input B | Second input set for each channel; routed to Y when S = H |
| 10–13 (1Y–4Y) | 3-State Output | Active-low when G = L; high-impedance when G = H |
| 14 (G) | Output Enable | Global 3-state control: Y outputs disabled (Z) when G = H |
| 8 (GND) | Ground Reference | Return path for all inputs/outputs; must be low-impedance connection |
| 16 (VCC) | Power Supply | Positive supply rail; bypass capacitor required near pin for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Quad 2:1 Multiplexing | Four independent channels reduce board space vs. discrete ICs; shared S/G pins simplify control wiring |
| 3-State Outputs | Enables direct connection to shared data buses without external isolation; prevents contention during disable |
| Wide VCC Range | 2–6 V operation allows use in 3.3 V microcontroller systems and legacy 5 V designs without voltage translation |
| Low Input Current | 1 µA max - minimizes loading on upstream logic and preserves fanout budget in large gate arrays |
| High Noise Immunity | VIL = 1.35 V / VIH = 3.15 V at VCC = 4.5 V - provides >1.8 V noise margin against ground bounce or crosstalk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-to-1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC258N | Same logic function, identical pinout, TI-manufactured; tpd = 13 ns typ (CL = 50 pF, VCC = 4.5 V) | Qualified to TI's industrial temp range (–40°C to +85°C); RoHS-compliant packaging differs | Drop-in replacement where TI sourcing is preferred; verify thermal derating for high-density layouts |
| MC74HC258N | Onsemi variant; identical AC/DC specs; absolute max ratings match (VCC = –0.5 to 7.0 V) | Available in same DIP-16 package but with different tape-and-reel options; lifecycle status differs | Valid alternative for long-term supply continuity; check Onsemi's PCN notifications for process changes |
Compared with 74HC258P-E, SN74HC258N offers marginally slower propagation but broader distributor availability, while MC74HC258N provides identical electrical performance with alternate supply chain resilience - both require no PCB changes but demand verification of thermal and ESD handling in final assembly.

FAQ
What is the maximum operating frequency supported by the 74HC258P-E?
The 74HC258P-E does not specify a maximum clock frequency in its datasheet because it is a combinational logic device without internal clocking. Its usable data rate depends on propagation delay and system timing margins: with 11 ns typical tpd (VCC = 4.5 V, CL = 50 pF), it supports reliable operation up to approximately 20 MHz in well-designed bus systems with controlled trace lengths and proper termination.
Does the 74HC258P-E support 3.3 V logic levels?
Yes, the 74HC258P-E supports 3.3 V operation within its rated 2–6 V supply range. At VCC = 3.3 V, VIH is guaranteed ≥ 2.31 V and VIL ≤ 1.09 V, providing adequate noise margin for interfacing with standard 3.3 V CMOS and LVTTL outputs. Input thresholds scale linearly with VCC, ensuring predictable switching behavior.
Can the 74HC258P-E outputs drive LEDs directly?
No, the 74HC258P-E outputs are not intended for direct LED driving. While its ±35 mA absolute maximum output current exceeds typical LED forward current (10–20 mA), the device lacks current-limiting capability and sustained DC drive rating. Driving LEDs requires external series resistors and thermal derating; for dedicated LED control, purpose-built drivers like the TLC5916 are recommended instead of the 74HC258P-E.
Is the 74HC258P-E RoHS compliant?
Yes, the 74HC258P-E is RoHS compliant per EU Directive 2011/65/EU. Renesas confirms compliance in its product change notifications and material declarations. The DIP-16 package uses lead-free terminations (Ni/Pd/Au plating) and halogen-free molding compound, meeting JEDEC J-STD-609A Class 1 requirements for moisture sensitivity and environmental safety.
What is the function of the G (pin 14) input on the 74HC258P-E?
The G (Output Enable) input on pin 14 of the 74HC258P-E controls the 3-state output buffer for all four Y outputs. When G = H (high), all Y outputs enter high-impedance (Z) state regardless of S or input states - effectively disconnecting them from the bus. When G = L (low), the multiplexer functions normally, routing selected A/B inputs to Y outputs based on the S signal. This enables bus sharing without contention.
