Product details
Overview
SN74HC153NG4 from Texas Instruments is a dual 4-line to 1-line data selector/multiplexer in PDIP-16 package, operating from 2 V to 6 V with typical propagation delay of 38 ns at 4.5 V and ±6-mA output drive capability. It implements binary-decoded channel selection with independent strobe (G) inputs per section and supports parallel-to-serial conversion in digital logic systems.
For engineers reviewing the SN74HC153NG4 datasheet, SN74HC153NG4 pinout, SN74HC153NG4 application, or SN74HC153NG4 equivalent, this page delivers verified functional modes, switching characteristics under CL = 50 pF, absolute maximum ratings, and real-world design implications for logic-level multiplexing in industrial control, test equipment, and data routing circuits.
Technical Context
The SN74HC153NG4 integrates two independent 4:1 multiplexer sections sharing common address inputs (A, B) but featuring separate strobe (G1, G2) and output (Y1, Y2) terminals. Each section decodes A/B to select one of four data inputs (C0–C3), with active-low enable logic forcing output low when strobe is high.
Its CMOS HC-family architecture ensures low static current (≤80 μA ICC), rail-to-rail output swing, and compatibility with LSTTL loads. Input transition time limits (400–1000 ns) and defined VIH/VIL thresholds ensure robust noise immunity across the full 2–6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 6 V - supports mixed-voltage system interfacing and battery-powered operation down to 2 V. |
| Propagation Delay (tpd) | 38 ns max at VCC = 4.5 V, CL = 50 pF - enables reliable timing in 20+ MHz digital control loops. |
| Output Drive Strength | ±6 mA at VCC = 5 V - directly drives 15 LSTTL loads without buffering in legacy TTL-compatible designs. |
| Input Leakage Current | ±1 μA max - prevents unintended logic state shifts in high-impedance or battery-critical nodes. |
| Power Consumption (ICC) | 80 μA max at VCC = 6 V - suitable for low-duty-cycle monitoring circuits where quiescent current matters. |
| Operating Temperature | –40 °C to +85 °C - qualified for commercial/industrial ambient environments without derating. |
Pinout & Package
SN74HC153NG4 uses a 16-pin plastic dual in-line package (PDIP-N) with 19.31 mm × 6.35 mm body size and through-hole mounting. Pin 1 is marked by a notch or dot; pin numbering follows standard DIP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G1) | Strobe input, Section 1 | Active-high enable: forces Y1 low when high; allows data routing only when low. |
| 2 (C01) | Data input 0, Section 1 | First of four selectable inputs for multiplexer section 1. |
| 3 (C11) | Data input 1, Section 1 | Second selectable input; selected when A=0, B=1. |
| 4 (C21) | Data input 2, Section 1 | Third selectable input; selected when A=1, B=0. |
| 5 (C31) | Data input 3, Section 1 | Fourth selectable input; selected when A=1, B=1. |
| 6 (Y1) | Output, Section 1 | Active-high routed output from Section 1; reflects selected Cx1 when G1 = low. |
| 7 (G2) | Strobe input, Section 2 | Independent enable for second multiplexer section; identical function to G1. |
| 8 (GND) | Ground reference | Primary return path for all internal logic and I/O; must be low-impedance. |
| 9 (C02) | Data input 0, Section 2 | First of four inputs for Section 2; shares A/B address lines with Section 1. |
| 10 (C12) | Data input 1, Section 2 | Second input for Section 2; decoding synchronized to same A/B signals. |
| 11 (C22) | Data input 2, Section 2 | Third input for Section 2; enables simultaneous dual-channel selection. |
| 12 (C32) | Data input 3, Section 2 | Fourth input for Section 2; supports independent data routing per section. |
| 13 (Y2) | Output, Section 2 | Active-high output from Section 2; isolated from Y1 electrically and functionally. |
| 14 (B) | Address select bit (LSB) | Shared binary address input; determines lower bit of 4-input selection (00–11). |
| 15 (A) | Address select bit (MSB) | Shared binary address input; determines upper bit of 4-input selection (00–11). |
| 16 (VCC) | Positive supply | Single power rail for both sections; bypass capacitor (0.1 μF) required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 multiplexers | Enables two simultaneous data routing paths using shared address lines-reduces PCB routing complexity vs. discrete mux ICs. |
| Strobe-controlled output enable | Separate G1/G2 pins allow dynamic disabling of each section without affecting address or data lines-critical for bus arbitration. |
| Wide 2–6 V supply range | Operates across legacy 5 V and modern low-voltage logic rails, eliminating level-shifter requirements in mixed-supply systems. |
| Low ICC (≤80 μA) | Minimizes standby power in always-on monitoring circuits such as sensor interface modules or fault-detection logic. |
| CMOS input compatibility | Accepts clean TTL or CMOS logic levels across full VCC range-no external pull-ups needed for unused inputs when tied to VCC/GND. |
Applications
| Industrial Control Logic | Test Equipment Signal Routing |
|---|---|
Use Scenario: Selecting among four analog sensor outputs (temperature, pressure, flow, humidity) before digitization in a PLC I/O module. IC Role / Device Role / Timing Role: Dual-channel data selector routing conditioned analog signals to a single ADC input under microcontroller address control.

FAQ
What is the maximum recommended supply voltage for SN74HC153NG4?
The absolute maximum supply voltage for SN74HC153NG4 is 7 V, but the recommended operating range is 2 V to 6 V per TI's SCLS112E datasheet. Operating continuously above 6 V risks permanent damage due to exceeding the specified maximum rating, even if within absolute limits. For reliable long-term operation, maintain VCC ≤ 6 V.
Does SN74HC153NG4 support independent address control for each multiplexer section?
No, SN74HC153NG4 does not support independent address control. Both sections share the same A and B address inputs (pins 14 and 15), meaning they simultaneously select the same input index (C0–C3) within their respective data groups. Independent selection requires external gating or separate address generation.
Can SN74HC153NG4 drive standard TTL loads directly?
Yes, SN74HC153NG4 can drive up to 15 LSTTL loads directly, as confirmed in its datasheet features. At VCC = 5 V, it provides ±6 mA output drive, meeting the current-sinking and sourcing requirements of LSTTL inputs. No external buffer is needed for standard TTL fanout in most implementations.
What is the function of the strobe (G) pins on SN74HC153NG4?
The strobe pins (G1 on pin 1, G2 on pin 7) are active-high enable inputs. When high, they force the corresponding output (Y1 or Y2) low regardless of address or data inputs. When low, the selected data input appears at the output. This allows independent gating of each multiplexer section without altering address lines.
Is SN74HC153NG4 RoHS compliant and lead-free?
Yes, SN74HC153NG4 is RoHS compliant and features lead-free (NIPDAU) termination, as documented in TI's PACKAGE OPTION ADDENDUM. Its PDIP package carries "G4" suffix indicating green packaging compliance, and it meets JEDEC J-STD-609 Category 1 marking standards for lead-free finish.
