Product details
Overview
SN74F153D from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer in a 16-pin SOIC package, operating at 4.5–5.5 V with propagation delays as low as 2.2 ns (tPHL for data-to-output), supporting parallel-to-serial conversion and cascaded multiplexing in TTL-compatible digital logic systems.
For engineers reviewing the SN74F153D datasheet, SN74F153D pinout, SN74F153D application, or SN74F153D equivalent, key selection criteria include its dual-section architecture with independent strobe inputs (1G, 2G), common select lines (A, B), guaranteed 20 mA low-level output drive, and commercial temperature range (0°C to 70°C) suitability for legacy industrial control and test equipment design.
Technical Context
The SN74F153D implements two independent 4:1 multiplexer sections sharing select inputs A and B, each with dedicated active-low strobe (1G, 2G) enabling cascading without external gating. Each section routes one of four data inputs (C0–C3) to its output (1Y or 2Y) based on binary select state.
Internal architecture includes inverters and drivers for full binary decoding, AND-OR logic gates for data selection, and TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V). Output stages deliver 20 mA sink current and support wired-OR configurations via open-collector-like behavior under load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V TTL logic rails and noise margin stability. |
| Propagation Delay (tPHL, C→Y) | 1.7 ns (min) to 7.5 ns (max) - Enables reliable operation in high-speed address/data routing up to ~100 MHz system clock domains. |
| Output Drive (IOL) | 20 mA - Sufficient to directly drive multiple 74F-series inputs or small LED indicators without buffering. |
| Input Thresholds | VIL = 0.8 V, VIH = 2.0 V - Matches standard TTL voltage levels for seamless integration into mixed-Family logic systems. |
| Operating Temperature | 0°C to 70°C - Qualified for commercial-grade embedded controllers, instrumentation, and office equipment. |
| Package | SOIC-16 (D) - Surface-mount footprint compatible with automated assembly and space-constrained PCB layouts. |
Pinout & Package
SN74F153D uses a 16-pin plastic small-outline integrated circuit (SOIC) package with 1.27 mm pitch, 7.5 mm body width, and 2.00 mm max height per TI NS0016A outline. Pin 1 identifier located at top-left corner with notch or beveled edge marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1C0 | Data input 0 for first multiplexer section - Active-high signal routed to 1Y when A=0, B=0 and 1G=L. |
| 2 | 1C1 | Data input 1 for first section - Selected when A=1, B=0 and 1G=L; shares select lines with all Cx inputs. |
| 3 | 1C2 | Data input 2 for first section - Selected when A=0, B=1 and 1G=L; enables full 4-input selection per section. |
| 4 | 1C3 | Data input 3 for first section - Selected when A=1, B=1 and 1G=L; completes binary decode coverage. |
| 5 | 1G | Active-low enable for first section - Forces 1Y = high-impedance when high; required for cascading or disabling. |
| 6 | 1Y | Inverted output of first section - Low-active output reflecting selected Cx input when 1G=L and A/B decoded. |
| 7 | GND | Ground reference - Shared return path for all internal logic and output stages; must be low-impedance. |
| 8 | 2C0 | Data input 0 for second multiplexer section - Independent data path mirroring 1C0 functionality. |
| 9 | 2Y | Inverted output of second section - Electrically isolated from 1Y; supports dual-channel routing on single IC. |
| 10 | 2C1 | Data input 1 for second section - Shares A/B select lines but operates independently under 2G control. |
| 11 | 2C2 | Data input 2 for second section - Enables simultaneous 4:1 selection on both sections using common address bus. |
| 12 | 2C3 | Data input 3 for second section - Completes second 4-input set; allows full 8-input → 2-output mapping with external OR. |
| 13 | 2G | Active-low enable for second section - Independent gating allows time-multiplexed or conditional routing. |
| 14 | VCC | +5 V power supply - Must be decoupled locally (0.1 µF ceramic) to suppress switching noise on shared rail. |
| 15 | B | Common select line (LSB) - Jointly controls both sections; reduces address bus loading vs. discrete muxes. |
| 16 | A | Common select line (MSB) - Paired with B to generate 2-bit decode; eliminates duplicate logic gates in system design. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 multiplexers | Reduces component count by integrating two functionally identical mux sections sharing select lines A/B. |
| Separate active-low strobe inputs (1G, 2G) | Enables selective section enable/disable for cascading, power gating, or conditional data routing without external logic. |
| TTL-compatible input/output levels | Guarantees interoperability with legacy 74F, 74LS, and 74AS families without level-shifting circuitry. |
| 20 mA output sink capability | Drives up to 10 standard TTL inputs or small indicator loads directly, eliminating buffer stages in many applications. |
| SOIC-16 surface-mount package | Supports automated PCB assembly and higher board density than through-hole DIP alternatives like SN74F153N. |

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 |
|---|---|---|---|
| SN74F153N | Same logic function and electrical specs, but in 16-pin PDIP package with through-hole mounting. | Suitable for prototyping, repair of legacy boards, or applications requiring manual assembly or socketing. | Select SN74F153N when board layout requires through-hole components or field-replaceable sockets. |
| SN74LS153 | Lower power consumption (ICC ≈ 19 mA vs. 20 mA), slower propagation (tPLH up to 22 ns), and reduced output drive (IOL = 8 mA). | Better suited for low-power, non-critical timing applications where speed < 25 MHz is acceptable. | Choose SN74LS153 only if system timing budget allows +12 ns delay margin and power savings outweigh performance loss. |
Compared with SN74F153N and SN74LS153, the SN74F153D delivers optimal balance of speed (sub-8 ns delay), SOIC packaging for modern assembly, and robust 20 mA drive-making it the preferred choice for new designs targeting commercial temperature range and automated manufacturing.

FAQ
What is the maximum operating frequency supported by the SN74F153D?
The SN74F153D does not specify a maximum clock frequency in its datasheet, but its worst-case propagation delay (tPHL/tPLH) is 12 ns for select-to-output paths. This supports reliable operation in digital systems with clock periods ≥24 ns, corresponding to a theoretical upper limit near 42 MHz for synchronous address/data routing applications involving the SN74F153D.
Can the SN74F153D be used in place of the SN74LS153 in an existing design?
The SN74F153D is functionally pin-compatible and electrically interoperable with the SN74LS153, but offers faster propagation delays (7.5 ns vs. 22 ns max) and higher output drive (20 mA vs. 8 mA). Substituting SN74F153D may improve timing margins but requires verifying that increased ICC (20 mA vs. 19 mA) and output transition rates do not induce noise in sensitive analog sections sharing the same SN74F153D supply rail.
Does the SN74F153D support hot-swap or live-insertion?
No, the SN74F153D is not designed for hot-swap operation. Its absolute maximum ratings specify no current-limiting or ESD-hardened inputs for live insertion, and applying VCC before GND or vice versa risks latch-up due to internal parasitic structures. Always power-cycle the board or use sequenced supply ramping when replacing the SN74F153D in-system.
What is the purpose of the NC pins on the SN74F153D package?
The SN74F153D has no NC (no-connect) pins in its SOIC-16 (D) package. All 16 pins are assigned functional roles as defined in the datasheet: pins 1–4 (1C0–1C3), 5 (1G), 6 (1Y), 7 (GND), 8 (2C0), 9 (2Y), 10–12 (2C1–2C3), 13 (2G), 14 (VCC), 15 (B), and 16 (A). Any reference to NC applies only to alternate packages like FK or J variants.
How does the strobe (G) input affect output behavior on the SN74F153D?
When the strobe input (1G or 2G) is high, the corresponding output (1Y or 2Y) is forced to a high-impedance (open-collector-like) state regardless of select or data inputs. When strobe is low, the output reflects the selected Cx input per the A/B decode state. This enables cascading, bus isolation, or conditional routing without additional logic gates in designs using the SN74F153D.
