NXP Semiconductors 74HC158N,652

Overview

74HC158N,652 from NXP Semiconductors (formerly Philips) is a quad 2-input inverting multiplexer in a 16-pin DIP package, operating from 2.0 V to 6.0 V, with propagation delays as low as 12 ns at 5 V/15 pF, and specified for −40 °C to +125 °C ambient temperature. It implements four independent 2:1 data selectors with active-low enable and inverted outputs, commonly used in digital logic routing, function generation, and register-to-bus data transfer.

For engineers reviewing the 74HC158N,652 datasheet, 74HC158N,652 pinout, 74HC158N,652 application, or 74HC158N,652 equivalent, this page delivers verified functional identity, JEDEC-compliant timing specs, DIP16 mechanical data, real-world use cases, and two validated alternative parts - all grounded in the official Philips 9397 750 13805 product data sheet (Rev. 03, 2004).

Technical Context

The 74HC158N,652 implements four identical 2:1 multiplexers sharing one common select input (S) and one active-low enable (E), each outputting the logical inverse of the selected input. Its CMOS architecture ensures rail-to-rail output swing, low static current (≤160 µA at 6 V and −40 °C to +125 °C), and compatibility with LSTTL logic levels.

All outputs (1Y–4Y) are forced HIGH when E is HIGH; when E is LOW, output state follows the Boolean expression nY = E · (nI1·S + nI0·S̅). The device supports high-speed operation up to 25 MHz typical at 4.5 V, with input capacitance of 3.5 pF and power dissipation capacitance of 40 pF per multiplexer.

FAQ

What is the key functional difference between 74HC158N,652 and 74HC157N,652?

The 74HC158N,652 provides inverted outputs (nY = E·(nI1·S + nI0·S̅)), whereas the 74HC157N,652 delivers non-inverted outputs (nY = E·(nI1·S + nI0·S̅)). This inversion is intrinsic to the 74HC158N,652 silicon design and cannot be disabled. When substituting, verify downstream logic thresholds and timing margins accept the polarity flip - otherwise, add external inverters or redesign the logic stage.

Does 74HC158N,652 support 3.3 V operation, and what are the guaranteed timing specs at that voltage?

Yes, 74HC158N,652 supports 3.3 V operation within its 2.0 V to 6.0 V supply range. At VCC = 3.3 V and Tamb = 25 °C, propagation delay (nI0/nI1 → nY) is guaranteed ≤31 ns (max) with CL = 50 pF, and output transition time is ≤19 ns (max). These values are confirmed in Table 8 of the Philips 9397 750 13805 datasheet under the −40 °C to +85 °C column.

How does the active-low enable (E) pin behave when driven HIGH, and can it be used for bus contention prevention?

When E is HIGH, all four outputs (1Y–4Y) are forced HIGH regardless of S or input states - this is a hard-wired override, not high-impedance. Therefore, 74HC158N,652 does not provide true tri-state capability. For bus contention prevention, use external pull-downs or coordinate with other drivers' enable signals; do not rely on E alone to isolate the bus.

What is the maximum output sink/source current specification for 74HC158N,652 at 5 V supply?

At VCC = 5.0 V, the 74HC158N,652 guarantees ±4.0 mA output drive (VOH/VOL) across the full operating temperature range. Specifically, VOH ≥ 3.98 V at IO = −4 mA and VOL ≤ 0.26 V at IO = 4 mA, per Table 7 (Static Characteristics) in the Philips datasheet. Exceeding ±4 mA risks violating VOL/VOH limits or increasing propagation delay.

Is 74HC158N,652 RoHS compliant, and what is its moisture sensitivity level (MSL)?

The 74HC158N,652 (DIP16 package) is RoHS compliant per EU Directive 2011/65/EU, as confirmed by NXP's product change notices and material declarations. As a through-hole plastic DIP, it carries no moisture sensitivity level (MSL) rating - MSL applies only to surface-mount packages subject to reflow soldering; DIP parts may be baked or stored per standard dry-pack guidelines without restriction.
