Product details
Overview
74HCT153DB,118 from Nexperia is a dual 4-input multiplexer IC with TTL-compatible input thresholds, 4.5 V to 5.5 V supply operation, independent active-low enable inputs (1E, 2E), shared binary select lines (S0, S1), and non-inverting outputs (1Y, 2Y). It routes one of four data inputs per channel to its output based on select logic, enabling signal routing in digital control logic, address decoding, and bus management systems.
For engineers reviewing the 74HCT153DB,118 datasheet, 74HCT153DB,118 pinout, 74HCT153DB,118 application, or 74HCT153DB,118 equivalent, key selection considerations include TTL-level input compatibility, -40 °C to +125 °C industrial temperature range, SO16 package footprint, propagation delay under 51 ns at 5 V, and dual-channel independent enable control for cascaded multiplexing.
Technical Context
The 74HCT153DB,118 implements two independent 4:1 multiplexers sharing S0/S1 select lines but featuring separate /1E and /2E enable inputs-allowing asynchronous channel gating. Each multiplexer selects one of four inputs (1I0–1I3 or 2I0–2I3) using a 2-bit binary code applied to S0/S1, with output asserted only when its respective enable is LOW.
Input clamping diodes permit interface to voltages exceeding VCC when used with current-limiting resistors. The device complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), supports HBM ESD >2000 V and CDM >1000 V, and operates across -40 °C to +125 °C with static VIH/VIL thresholds fixed at 2.0 V/0.8 V (TTL-compatible) at VCC = 4.5–5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures reliable interoperability with standard 5 V TTL logic families without level shifting. |
| Propagation Delay (tPD) | 19–51 ns at VCC = 4.5 V - Supports high-speed digital routing up to ~10 MHz system clock domains with predictable timing margins. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - Guarantees robust recognition of standard TTL output levels (e.g., 74LS, 74F) without false switching. |
| Output Drive | ±4.0 mA (VOH/VOL) - Sufficient to drive 10 LS-TTL loads or directly interface with microcontroller GPIOs and FPGA I/O banks. |
| Operating Temperature | -40 °C to +125 °C - Qualified for industrial and extended-temperature embedded control applications including motor drives and power supplies. |
| Power Dissipation | CPD = 30 pF - Enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal design in dense PCB layouts. |
Pinout & Package
74HCT153DB,118 is housed in a plastic small outline package (SO16), also known as SOT109-1, with 16 leads and 3.9 mm body width. Pin 1 is marked by a notch or dot; the package is RoHS-compliant and rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1E, 2E | Active-low enable inputs - Asserting either LOW enables its corresponding multiplexer; HIGH forces output LOW (high-impedance not supported). |
| 2, 14 | S1, S0 | Common binary select inputs - Shared between both multiplexers; define which of four inputs (00–11) is routed to output. |
| 3–6, 10–13 | 1I0–1I3, 2I0–2I3 | Data input terminals - Two independent sets of four inputs; each set feeds one multiplexer channel. |
| 7, 9 | 1Y, 2Y | Non-inverting multiplexer outputs - Output reflects selected input state; no polarity inversion or buffering delay added. |
| 8 | GND | Ground reference - All voltage measurements and logic thresholds referenced to this node; must be low-impedance. |
| 16 | VCC | Positive supply - Powers internal CMOS circuitry; requires local 100 nF decoupling near pin for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V - Eliminates need for external level shifters when interfacing with legacy 74LS or microcontroller outputs. |
| Dual independent enables | Separate /1E and /2E pins - Enables selective activation of each multiplexer for time-multiplexed signal routing or power-gated channel control. |
| Clamp diode protection | Integrated input clamp diodes - Allows safe connection to signals up to VCC + 0.5 V using series current-limiting resistors. |
| Cascadable architecture | Shared S0/S1 with individual enables - Supports n:1 expansion (e.g., eight inputs → one output) using multiple devices with minimal control logic. |
| Industrial temperature range | -40 °C to +125 °C operation - Validated for use in motor controllers, industrial PLC I/O modules, and power supply monitoring circuits. |
Applications
| Industrial Control Logic | Microcontroller Peripheral Multiplexing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC153D,118 | CMOS input thresholds (VIH = 3.15 V min at VCC = 4.5 V); wider 2.0–6.0 V supply range. | Requires 3.3 V or higher logic levels for reliable HIGH detection; unsuitable for direct 74LS interface. | Select when operating from 3.3 V or mixed-voltage systems where TTL compatibility is unnecessary. |
| SN74LS153N | Bipolar TTL technology; VIH = 2.0 V, VIL = 0.8 V same, but higher ICC (19 mA typical), slower tPD (~25 ns), and narrower temp range (-55 to +125 °C). | Higher power draw and lower noise immunity; lacks clamp diodes and modern ESD ratings. | Select only for legacy board replacements where pinout and timing match existing LS designs exactly. |
Compared with 74HC153D,118, the 74HCT153DB,118 offers guaranteed TTL-level input compatibility at 5 V, while SN74LS153N provides identical logic behavior but with higher power, lower ESD robustness, and no modern packaging options-making the HCT variant optimal for new industrial designs requiring reliability and interoperability.

FAQ
What is the maximum clock frequency supported by the 74HCT153DB,118?
The 74HCT153DB,118 does not operate on a clock; it is a combinational logic device whose output responds asynchronously to input and select changes. Its usable signal switching rate is governed by propagation delay (≤51 ns at VCC = 4.5 V) and transition time (≤22 ns), supporting reliable operation up to approximately 10 MHz in synchronous control applications with adequate setup/hold margins.
Can the 74HCT153DB,118 be used with a 3.3 V supply?
No-the 74HCT153DB,118 is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds (VIH ≥ 2.0 V) may still be met, but VOH/VOL performance, propagation delay, and noise margins are not guaranteed. For 3.3 V systems, use the 74LVC153 or 74AUP1G153 series instead.
Is the 74HCT153DB,118 pin-compatible with the 74HC153D,118?
Yes-both share identical SO16 (SOT109-1) pinout, pin functions, and electrical connections. However, their input threshold specifications differ: 74HCT153DB,118 accepts TTL-level inputs (VIH ≥ 2.0 V), while 74HC153D,118 requires CMOS-level inputs (VIH ≥ 3.15 V at 4.5 V), making them functionally interchangeable only when driving logic levels meet both specs.
Does the 74HCT153DB,118 support high-impedance (tri-state) outputs?
No-it features push-pull, non-inverting outputs with no tri-state capability. When an enable input (/1E or /2E) is HIGH, the corresponding output is forced LOW-not high-impedance. For true tri-state multiplexing, consider the 74LVCH162374 or dedicated bus switch ICs like the NX3L4684.
