Product details
Overview
74HC258N,652 from NXP Semiconductors is a quad 2-input CMOS multiplexer with inverting 3-state outputs, pin-compatible with LSTTL, operating from −40 °C to +125 °C with supply voltage range 2.0–6.0 V and propagation delay as low as 9 ns at VCC = 6.0 V. It functions as a logic-controlled 4-pole, 2-position switch for data routing in bus-interfaced digital systems.
For engineers reviewing the 74HC258N,652 datasheet, 74HC258N,652 pinout, 74HC258N,652 application, or 74HC258N,652 equivalent, key selection criteria include its inverting output behavior, common select (S) and active-low output enable (OE), 3-state bus interface capability, and DIP16 package compatibility with legacy through-hole designs.
Technical Context
The 74HC258N,652 implements four independent 2:1 multiplexers sharing one data select input (S) and one active-low output enable (OE). Each output (1Y–4Y) is inverted relative to its selected input (nI0 or nI1), and all outputs enter high-impedance state when OE is HIGH.
Its logic equations follow Yn = OE × (S̅ × nI0 + S × nI1), confirming strict inverting behavior and 3-state control. The device complies with JEDEC standard no. 7A and supports operation across industrial and extended temperature ranges up to +125 °C.

Pinout & Package
74HC258N,652 uses a plastic dual in-line package (DIP16) with 300-mil lead spacing, suitable for through-hole mounting and prototyping. Pin 1 is the common data select input (S); pins 2–3, 5–6, 10–11, and 13–14 are paired data inputs; pins 4, 7, 9, and 12 are inverted 3-state outputs; pin 15 is active-low output enable (OE); pins 8 (GND) and 16 (VCC) provide power rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Common data select input | Controls source selection for all four multiplexers: LOW selects source 0 (nI0), HIGH selects source 1 (nI1) |
| 2 (1I0), 3 (1I1) | Data inputs for channel 1 | Provide complementary data sources to first multiplexer; output 1Y is inverted combination |
| 4 (1Y) | Inverting 3-state output 1 | Delivers inverted selected input; enters high-Z when OE = HIGH |
| 5 (2I0), 6 (2I1) | Data inputs for channel 2 | Independent pair routed to second multiplexer; identical logic to channel 1 |
| 7 (2Y) | Inverting 3-state output 2 | Matches 1Y behavior with separate data path; enables parallel 4-bit selection |
| 8 (GND) | Ground reference | 0 V return path for all internal logic and I/O; must be low-impedance for noise immunity |
| 9 (3Y), 12 (4Y) | Inverting 3-state outputs 3 & 4 | Complete quad-channel set; allows simultaneous 4-bit bus switching with inversion |
| 10 (3I1), 11 (3I0), 13 (4I1), 14 (4I0) | Data inputs for channels 3 & 4 | Full 4×2 input matrix supporting byte-wide data routing applications |
| 15 (OE) | Active-low output enable | Global control: HIGH forces all outputs into high-impedance state, enabling bus sharing |
| 16 (VCC) | Positive supply voltage | Primary power rail; decoupling capacitor required near pin for stable high-speed operation |

FAQ
What is the logic function of the 74HC258N,652?
The 74HC258N,652 implements four independent 2:1 multiplexers with a common select input (S) and active-low output enable (OE). Each output (1Y–4Y) delivers the inverted value of the selected input: when S = LOW, nI0 is passed and inverted; when S = HIGH, nI1 is passed and inverted. All outputs go high-impedance when OE = HIGH. This behavior is defined in the logic equations on page 2 of the NXP datasheet Rev. 04.
Does the 74HC258N,652 support 3.3 V operation?
Yes, the 74HC258N,652 supports 3.3 V operation within its recommended supply range of 2.0 V to 6.0 V. At VCC = 3.3 V, VIH is 2.31 V and VIL is 1.09 V (calculated per datasheet Table 6 interpolation), providing >1.1 V noise margin. Propagation delay is approximately 15 ns (interpolated from 2.0 V and 4.5 V data), making it suitable for mixed-voltage 3.3 V/5 V system interfaces.
What is the maximum clock/data rate supported by the 74HC258N,652?
The 74HC258N,652 does not operate on a clock; it is combinational logic. Its maximum usable data rate is determined by propagation delay and transition time. With tpd = 9 ns (typical at VCC = 6.0 V) and tt = 4 ns (typical), the device supports clean signal routing up to ~50 MHz for single-cycle selection events. For sustained toggling, system-level timing analysis must account for worst-case delays (25 ns at 125 °C) and load capacitance.
How does the 74HC258N,652 differ from the 74HC257N,652?
The 74HC258N,652 and 74HC257N,652 share identical pinout, supply range, temperature rating, and multiplexer structure-but the 74HC258N,652 has inverting outputs while the 74HC257N,652 has non-inverting outputs. This difference affects downstream logic: 74HC258N,652 requires no external inverters when driving inverting loads (e.g., certain latches), whereas 74HC257N,652 preserves input polarity. Both use the same DIP16 package.
Is the 74HC258N,652 RoHS compliant and halogen-free?
Yes, the 74HC258N,652 is RoHS compliant and halogen-free per NXP's product compliance documentation. The "N" suffix in the part number denotes a lead-free, RoHS-compliant DIP package (SOT38-4), and NXP confirms halogen-free status for this package variant in its material declarations. Full compliance reports are available via NXP's Quality & Reliability portal using document ID 74HC258_4.
