Product details
Overview
74HC138D,653 from Nexperia is a 3-to-8 line inverting decoder/demultiplexer in SO16 package, operating from 2.0 V to 6.0 V supply, featuring three enable inputs (E1, E2 active LOW; E3 active HIGH), eight mutually exclusive active LOW outputs (Y0–Y7), and specified for -40 °C to +125 °C industrial temperature range. It enables memory chip select decoding and scalable 1-of-32 expansion using four ICs and one inverter.
For engineers reviewing the 74HC138D,653 datasheet, 74HC138D,653 pinout, 74HC138D,653 application, or 74HC138D,653 equivalent, this page delivers verified functional behavior, SO16 pin mapping, propagation delay (15 ns typ @ 4.5 V), static input/output voltage thresholds, and real-world demultiplexing use cases - all confirmed from Nexperia's Rev. 10 product data sheet.
Technical Context
The 74HC138D,653 implements combinational logic decoding with strict mutual exclusivity: only one output goes LOW when all three enables are satisfied (E1=L, E2=L, E3=H) and address inputs A0–A2 match a unique 3-bit code. Its enable architecture supports cascading without external logic - E1/E2/E3 allow hierarchical control of multiple decoders in memory or I/O selection trees.
It uses standard CMOS silicon with input clamp diodes enabling overvoltage-tolerant interfacing via current-limiting resistors, and meets JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards. Static noise immunity exceeds 40% of VCC, and latch-up performance exceeds 100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered operation down to 2 V. |
| Propagation Delay | 15 ns typical (A0–A2 to Yn @ VCC = 4.5 V, CL = 50 pF) - enables reliable timing in 33 MHz address decode paths. |
| Output Drive | ±4.0 mA (VOH/VOL @ VCC = 4.5 V) - sufficient to directly drive TTL loads or multiple 74HC inputs without buffering. |
| Input Thresholds | VIH = 3.15 V, VIL = 1.35 V @ VCC = 4.5 V - ensures robust CMOS-level noise margin (>1.8 V) in noisy industrial environments. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, motor drives, and industrial PLC backplanes. |
| Power Dissipation | 500 mW max (SO16 package) - derates linearly above 110 °C (12.4 mW/K), supporting sustained high-temp operation. |
| ESD Protection | HBM >2000 V, CDM >1000 V - eliminates need for external ESD protection in board-level designs. |
Pinout & Package
74HC138D,653 is housed in SO16 (SOT109-1) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | A0, A1, A2 | Binary address inputs - determine which of eight outputs (Y0–Y7) activates LOW; LSB-aligned (A0 = pin 1). |
| 4, 5 | E1, E2 | Active LOW enable inputs - both must be LOW for decoding to occur; used for hierarchical chip select gating. |
| 6 | E3 | Active HIGH enable input - complements E1/E2 to form three-input AND gate controlling overall device activation. |
| 7, 9–15 | Y0, Y1, Y2, Y3, Y4, Y5, Y6, Y7 | Active LOW decoded outputs - only one asserts LOW per valid address/enable combination; open-drain compatible via pull-ups. |
| 8 | GND | Ground reference - mandatory 0 V return path; decoupling capacitor must be placed adjacent to pin 8. |
| 16 | VCC | Positive supply - accepts 2.0–6.0 V; requires local 100 nF ceramic bypass capacitor between pins 8 and 16. |
Key Features
| Feature | Design Value |
|---|---|
| Multiple Enable Architecture | Three independent enables (E1/E2 LOW, E3 HIGH) allow daisy-chaining up to four 74HC138D ICs for 5-to-32 line decoding without extra gates. |
| Inverting Output Logic | All eight outputs are active LOW and mutually exclusive - simplifies connection to active-low chip selects (e.g., SRAM /CS, Flash /CE). |
| Overvoltage-Tolerant Inputs | Clamp diodes on all inputs permit safe interface to signals up to VCC + 0.5 V using series current-limiting resistors. |
| Wide Temperature Range | Specified from -40 °C to +125 °C - validated for continuous operation in motor control enclosures and power supply management circuits. |
| Low Dynamic Power | CPD = 67 pF - enables sub-mW dynamic power at 1 MHz toggle rate (PD ≈ 1.5 mW @ VCC = 5 V), critical for low-power embedded systems. |
Applications
| Memory Address Decoding | Industrial I/O Expansion |
|---|---|
|
Use Scenario: Selecting one of eight SRAM or EEPROM chips in a microcontroller-based data logger with limited GPIO. IC Role / Device Role: 3-bit address decoder generating active LOW /CS signals for parallel memory banks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-to-8 decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT138D,653 | TTL-compatible inputs (VIH = 2.0 V min @ VCC = 4.5 V); identical pinout and function. | Better interoperability with legacy 5 V TTL logic families; slightly higher ICC (80 μA max vs. 160 μA for HC). | Select when interfacing with 74LS or 74F series; avoid if system uses pure CMOS signaling below 3.3 V. |
| SN74LS138N | Bipolar TTL process; VCC = 4.75–5.25 V only; propagation delay ~22 ns; higher ICC (~24 mA). | Requires strict 5 V supply; not suitable for 3.3 V or battery-powered designs; generates more heat. | Use only in legacy 5 V TTL systems where HC/HCT noise immunity or wide VCC range is unnecessary. |
Compared with 74HCT138D,653 and SN74LS138N, the 74HC138D,653 offers lowest power (8 μA ICC typ), widest supply range (2–6 V), and best noise margin - making it optimal for modern mixed-voltage embedded systems requiring reliability across temperature extremes.

FAQ
Can 74HC138D,653 operate at 3.3 V supply?
Yes. The 74HC138D,653 is fully specified from 2.0 V to 6.0 V, including 3.3 V operation. At VCC = 3.3 V, VIH = 2.31 V min and VIL = 1.09 V max ensure compatibility with 3.3 V CMOS logic families, and propagation delay remains ≤25 ns (typical) with CL = 50 pF.
Is 74HC138D,653 pin-compatible with 74HCT138D,653?
Yes - both share identical SO16 (SOT109-1) pinout, pin functions, and mechanical footprint. The only functional difference is input threshold levels: 74HC138D uses CMOS thresholds (VIH ≈ 0.7×VCC), while 74HCT138D uses TTL thresholds (VIH = 2.0 V fixed). No PCB redesign is needed for substitution.
What is the maximum clock/data toggle rate supported?
The 74HC138D,653 is combinational (not clocked), so its speed is governed by propagation delay and transition time. With tpd = 15 ns (typ) and tt = 7 ns (typ) at 4.5 V, it reliably supports address/data switching up to ~33 MHz in worst-case path analysis, assuming proper layout and load capacitance ≤50 pF.
Does it support 3-state outputs?
No. The 74HC138D,653 has standard push-pull CMOS outputs with active LOW assertion - no high-impedance (3-state) capability. Outputs are always driven HIGH or LOW based on enable/address conditions. For bus-sharing applications, external tri-state buffers or open-drain configurations with pull-ups are required.
