Product details
Overview
SN74HC153PW from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer in TSSOP-16 package, operating from 2 V to 6 V supply, with typical propagation delay of 17 ns at 6 V and ±6-mA output drive capability at 5 V. It performs parallel-to-serial conversion in digital logic systems requiring channel selection under shared address control.
For engineers reviewing the SN74HC153PW datasheet, SN74HC153PW pinout, SN74HC153PW application, or SN74HC153PW equivalent, this page delivers verified functional modes, switching characteristics, thermal metrics, and real-world use cases for logic-level multiplexing in industrial control, test equipment, and embedded I/O expansion.
Technical Context
The SN74HC153PW implements two independent 4:1 multiplexer channels sharing common binary select inputs (A, B) and individual strobe (G) enables. Each channel decodes A/B to route one of four data inputs (C0–C3) to its output (Y), with active-low enable logic forcing Y low when G = HIGH.
Its CMOS HC-family architecture ensures low static current (≤80 μA ICC), high noise immunity (VIH/VIL thresholds defined across 2–6 V), and compatibility with LSTTL loads-enabling direct interface with legacy logic without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2 V to 6 V - supports mixed-voltage system integration and battery-powered operation down to 2 V. |
| Propagation Delay (tpd) | 17 ns max at VCC = 6 V, CL = 50 pF - enables reliable timing in 50-MHz-class synchronous logic paths. |
| Output Drive | ±6 mA at VCC = 5 V - sufficient to directly drive 15 LSTTL inputs or small capacitive loads without buffering. |
| Input Leakage Current | ±1 μA max - ensures stable logic states with high-impedance sources or pull-up/pull-down networks. |
| Power Dissipation Capacitance | 40 pF per multiplexer - used with frequency and supply voltage to calculate dynamic power consumption. |
| Junction-to-Ambient θJA | 108 °C/W (TSSOP-16) - informs thermal derating limits for continuous operation at ambient >60 °C. |
Pinout & Package
TSSOP-16 package: 5.00 mm × 4.40 mm body, 0.65 mm lead pitch, 1.2 mm max height, RoHS-compliant NiPdAu/Sn lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Channel 1 Strobe Enable | Active-HIGH disable: forces Y1 LOW regardless of select or data inputs; used for cascading or gating. |
| 2 (C01) | Channel 1 Data Input 0 | Low-order input selected when A=0, B=0; tied to system data bus or sensor output. |
| 3 (C11) | Channel 1 Data Input 1 | Second input selected when A=1, B=0; supports 4-bit parallel selection per channel. |
| 4 (C21) | Channel 1 Data Input 2 | Third input selected when A=0, B=1; enables flexible routing of analog/digital signals via logic control. |
| 5 (C31) | Channel 1 Data Input 3 | High-order input selected when A=1, B=1; completes full binary decoding for 4:1 selection. |
| 6 (A) | Common Address Select LSB | Shared between both channels; determines lower bit of 2-bit select code for simultaneous dual-channel routing. |
| 7 (B) | Common Address Select MSB | Shared between both channels; determines upper bit of 2-bit select code; reduces control line count. |
| 8 (GND) | Ground Reference | Return path for all internal logic and I/O; must be low-impedance and adjacent to bypass capacitor. |
| 9 (Y2) | Channel 2 Output | Inverted-logic output (active-HIGH) of second 4:1 mux; drives downstream latch or bus transceiver. |
| 10 (C02) | Channel 2 Data Input 0 | Independent data source for second channel; allows dual independent 4:1 functions on single IC. |
| 11 (C12) | Channel 2 Data Input 1 | Enables time-division multiplexing of two separate signal groups using shared address lines. |
| 12 (C22) | Channel 2 Data Input 2 | Supports redundant or mirrored signal paths where identical selection logic applies to both channels. |
| 13 (C32) | Channel 2 Data Input 3 | Completes second 4-input set; permits dual 4:1 operation without external glue logic. |
| 14 (VCC) | Positive Supply | 2–6 V CMOS supply rail; requires local 0.1-μF ceramic bypass capacitor placed within 3 mm of pin. |
| 15 (Y1) | Channel 1 Output | Primary output for first 4:1 section; routed to microcontroller GPIO or FPGA I/O bank. |
| 16 (NC) | No Internal Connection | Unused pin; must remain unconnected - not grounded or tied to VCC to avoid mechanical stress or EMI coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 multiplexers | Reduces board space and component count vs. two discrete 74HC151s; shares address lines to minimize MCU GPIO usage. |

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 |
|---|---|---|---|
| SN74LV153PW | Lower VCC range (1.65–5.5 V); faster tpd (13 ns @ 5 V); higher ICC (100 μA typ) | Better suited for 1.8 V/3.3 V-only systems; less tolerant of 5 V legacy interfaces | Select when migrating to LV-family for speed/power trade-off in modern low-voltage designs. |
| 74AHC153PW | Wider VCC (2–5.5 V); higher drive (±8 mA); lower Cpd (30 pF); same pinout | Superior noise immunity and rise/fall times; optimized for high-speed board-level signaling | Prefer for designs requiring <10 ns propagation or driving >20 pF loads without degradation. |
Compared with SN74HC153PW, SN74LV153PW offers improved speed at lower voltages but sacrifices 5 V tolerance, while 74AHC153PW delivers higher drive strength and lower capacitance-making it ideal for timing-critical, high-fanout routing where HC's 17 ns delay or 6 mA drive becomes limiting.

FAQ
What is the maximum operating temperature for the SN74HC153PW?
The SN74HC153PW is rated for operation from −40 °C to +85 °C ambient temperature, matching the commercial-grade specification of the 74HC logic family. Its TSSOP-16 package has a junction-to-ambient thermal resistance of 108 °C/W, so sustained operation near the upper limit requires attention to PCB copper area and airflow. The SN74HC153PW datasheet specifies no derating below 85 °C, and thermal shutdown is not implemented - design margin must be maintained via layout and system-level cooling.
Can the SN74HC153PW operate reliably at 3.3 V supply?
Yes, the SN74HC153PW operates reliably at 3.3 V supply, as confirmed by TI's Recommended Operating Conditions: VCC = 2 V to 6 V, with VIH = 2.0 V min and VIL = 1.0 V max at 3.3 V. At this voltage, typical propagation delay is 23 ns (CL = 50 pF), output drive is ±4.2 mA, and ICC remains ≤80 μA. The SN74HC153PW maintains full logic functionality and noise margins across the entire 3.3 V rail, making it suitable for mixed-signal systems interfacing with 3.3 V microcontrollers.
Is the SN74HC153PW pin-compatible with other 74HC153 package variants?
Yes, the SN74HC153PW shares identical pin numbering and function mapping with all 16-pin variants (D, N, NS, W, J packages) per TI's Pin Configuration documentation. Pin 1 is G1, Pin 16 is NC, and all signal names (A, B, C01–C32, Y1, Y2, GND, VCC) align exactly. However, mechanical dimensions, thermal performance (θJA = 108 °C/W for PW vs. 64 °C/W for NS), and moisture sensitivity (MSL-1 for PW vs. MSL-1 for D/NS) differ - PCB footprints and reflow profiles must be validated per package drawing PW0016A.
Does the SN74HC153PW support hot insertion or live swapping?
No, the SN74HC153PW does not support hot insertion. Its absolute maximum ratings specify no current injection limits during power sequencing, and the device lacks bus-hold or power-up 3-state circuitry. Applying signal inputs before VCC stabilization may cause latch-up or excessive ICC. TI recommends powering VCC and GND first, then applying inputs - the SN74HC153PW must be powered and stable before any logic signals are asserted, per Section 5.2 of the datasheet.
How does the strobe (G) input affect output behavior in the SN74HC153PW?
The strobe (G) input on each channel of the SN74HC153PW is active-HIGH and overrides all data and select inputs: when G = HIGH, the corresponding Y output is forced LOW regardless of A, B, or Cx states. When G = LOW, normal 4:1 selection resumes. This enables cascading (e.g., using one SN74HC153PW's Y output to enable another's G input) or time-gated sampling. The SN74HC153PW's G inputs are electrically isolated between channels, allowing independent enable control for dual-path routing.
