Product details
Overview
SN74HC153PWR 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. It implements full binary decoding for channel selection, features independent strobe (G) inputs per section, and supports parallel-to-serial conversion in digital logic systems.
For engineers reviewing the SN74HC153PWR datasheet, SN74HC153PWR pinout, SN74HC153PWR application, or SN74HC153PWR equivalent, key selection criteria include its dual-channel multiplexing function, 16-pin TSSOP footprint, 2–6 V wide supply range, low ICC (80 μA max), and compatibility with LSTTL loads.
Technical Context
The SN74HC153PWR integrates two independent 4:1 multiplexer sections sharing common address inputs (A, B) but each with dedicated strobe (G1, G2) and output (Y1, Y2) terminals. Its internal architecture uses inverters, drivers, and AND-OR logic to perform binary-decoded data routing without external decoding logic.
Each section selects one of four data inputs (C0–C3) based on A/B state, while active-high strobe disables output (forces Y low). The device operates in standard CMOS logic family with rail-to-rail input thresholds and complementary output structure, enabling direct interface with HC, HCT, and LS families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2 V to 6 V - enables interoperability across mixed-voltage digital systems including 3.3 V and 5 V rails |
| Propagation Delay (tpd) | 17 ns (max) at VCC = 6 V - supports high-speed data routing up to ~30 MHz toggle rate in combinatorial paths |
| Output Drive | ±6 mA at VCC = 5 V - sufficient to directly drive 15 LSTTL loads without buffering |
| Quiescent Current (ICC) | 80 μA (max) - ensures ultra-low static power in battery-backed or energy-sensitive control logic |
| Input Leakage | 1 μA (max) - prevents unintended logic transitions when inputs are tied to high-impedance sources or pull-ups |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial-grade embedded control and instrumentation applications |
Pinout & Package
TSSOP-16 package (PW), 5.00 mm × 4.40 mm body size, 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) | Strobe input, Section 1 | Active-high enable: Y1 = LOW when G1 = HIGH; overrides data selection |
| 2 (C0_1) | Data input, Section 1 | First of four selectable inputs for first multiplexer channel |
| 3 (C1_1) | Data input, Section 1 | Second selectable input for first channel; routed to Y1 when A=0,B=0 |
| 4 (C2_1) | Data input, Section 1 | Third selectable input for first channel; routed to Y1 when A=1,B=0 |
| 5 (C3_1) | Data input, Section 1 | Fourth selectable input for first channel; routed to Y1 when A=1,B=1 |
| 6 (Y1) | Output, Section 1 | Inverted output of selected Cx_1 input when G1 = LOW; open-drain not supported |
| 7 (G2) | Strobe input, Section 2 | Independent enable for second multiplexer section; identical function to G1 |
| 8 (C0_2) | Data input, Section 2 | First of four inputs for second channel; shares A/B select lines with Section 1 |
| 9 (C1_2) | Data input, Section 2 | Second input for Section 2; selected under same A/B conditions as C1_1 |
| 10 (C2_2) | Data input, Section 2 | Third input for Section 2; allows simultaneous dual-path selection with shared addressing |
| 11 (C3_2) | Data input, Section 2 | Fourth input for Section 2; enables synchronized dual 4:1 routing |
| 12 (Y2) | Output, Section 2 | Output of second multiplexer; electrically isolated from Y1 except via shared VCC/GND |
| 13 (B) | Address select input | Binary LSB for both sections; determines C0/C1 vs C2/C3 group selection |
| 14 (A) | Address select input | Binary MSB for both sections; completes 2-bit decode for full 4-input selection |
| 15 (VCC) | Positive supply | Single 2–6 V rail powers both sections; requires local 0.1-μF bypass capacitor |
| 16 (GND) | Ground reference | Common return for all logic and output currents; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| SN74HCT153PWR | TTL-compatible input thresholds (VIH = 2 V min at VCC = 4.5 V); otherwise identical pinout, timing, and drive | Better suited for mixed 5 V TTL/CMOS systems where input noise margin must match legacy TTL levels | Select SN74HCT153PWR when interfacing with 5 V TTL outputs; use SN74HC153PWR for pure CMOS or 3.3 V–5 V mixed-rail designs |
| 74LVX153MTR | Lower VCC range (2.7–3.6 V only); 3.3 V optimized; slightly higher tpd (22 ns typ at 3.3 V) | Targeted for low-voltage portable electronics; not suitable for 5 V operation or LSTTL load driving | Choose 74LVX153MTR only in strictly 3.3 V systems requiring minimal power; SN74HC153PWR remains preferred for industrial 2–6 V flexibility |
Compared with SN74HCT153PWR and 74LVX153MTR, the SN74HC153PWR offers the broadest supply range and highest output drive, making it optimal for general-purpose industrial and mixed-voltage digital logic where robustness and compatibility outweigh narrow-voltage optimization.

FAQ
What is the maximum clock frequency supported by SN74HC153PWR for data selection?
The SN74HC153PWR is a combinational logic device without an internal clock; its usable toggle rate depends on propagation delay and system setup/hold timing. With a typical tpd of 17 ns at 6 V, it supports reliable data routing at frequencies up to approximately 30 MHz in well-designed PCB layouts with controlled trace lengths and proper decoupling.
Can SN74HC153PWR operate reliably at 3.3 V supply?
Yes, SN74HC153PWR is fully specified for operation from 2 V to 6 V, including 3.3 V. At 3.3 V, it delivers ≥4.5 mA output drive, VIH ≈ 2.3 V, VIL ≈ 1.0 V, and tpd ≈ 23 ns (typ), making it compatible with standard 3.3 V CMOS logic families and mixed-voltage interfaces.
Does SN74HC153PWR require external pull-up or pull-down resistors on unused inputs?
Yes - all unused inputs (including A, B, G1, G2, and any unconnected Cx pins) must be tied to VCC or GND per TI's SCBA004 guidance. Floating CMOS inputs cause increased ICC, noise susceptibility, and potential oscillation; tying to valid logic levels ensures predictable operation and meets recommended operating conditions.
Is SN74HC153PWR pin-compatible with SN74HC153N (PDIP-16)?
Yes - SN74HC153PWR (TSSOP-16) and SN74HC153N (PDIP-16) share identical pin numbering, signal assignment, and electrical functionality. Only the physical package differs; PCB layout must accommodate TSSOP's 0.65 mm pitch and 5.0 × 4.4 mm footprint versus PDIP's 19.3 × 6.4 mm through-hole outline.
What thermal considerations apply to SN74HC153PWR in continuous operation?
SN74HC153PWR has a junction-to-ambient thermal resistance (RθJA) of 108 °C/W in TSSOP-16. At max ICC (80 μA) and worst-case output loading, self-heating is negligible. However, in high-output-drive scenarios (e.g., sustained ±6 mA), ensure adequate copper pour and airflow to maintain junction temperature below 125 °C under −40 °C to +85 °C ambient.
