Product details

Overview

74HC253PWHL from Nexperia is a dual 4-input CMOS multiplexer with independent 3-state outputs, shared S0/S1 select lines, and separate active-low output enable (1OE/2OE) inputs. It operates from 2.0 V to 6.0 V, delivers propagation delay as low as 16 ns at VCC = 6.0 V, and supports industrial temperature range (−40 °C to +125 °C). It is used in digital bus routing and data path selection within microcontroller peripheral interfaces.

For engineers reviewing the 74HC253PWHL datasheet, 74HC253PWHL pinout, 74HC253PWHL application, or 74HC253PWHL equivalent, key selection criteria include its dual-channel 4:1 multiplexing capability, TTL-compatible input thresholds (for 74HCT variant), non-inverting data path, 3-state bus interface compatibility, and TSSOP16 package thermal performance.

Technical Context

The device implements two independent 4:1 multiplexers sharing common select inputs (S0, S1), each with four binary data inputs (1I0–1I3 and 2I0–2I3), dedicated output enable (1OE, 2OE), and buffered non-inverting outputs (1Y, 2Y). Output enable is active-low and places the corresponding output in high-impedance state when asserted.

Input clamping diodes allow safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Static characteristics confirm VIH ≥ 3.15 V and VIL ≤ 1.35 V at VCC = 4.5 V (74HC), while dynamic timing specifies tpd = 17 ns (typ), ten = 9 ns (typ), and tdis = 12 ns (typ) at VCC = 6.0 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Function	Dual 4:1 multiplexer with independent 3-state outputs and shared select lines
Supply Voltage Range	2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-powered logic
Propagation Delay (tpd)	16 ns (typ) at VCC = 6.0 V - enables operation in 50 MHz+ address/data switching paths
Output Enable Timing	ten = 9 ns, tdis = 12 ns (typ) at VCC = 6.0 V - ensures tight bus arbitration window control
Input Thresholds (74HC)	VIH = 3.15 V min, VIL = 1.35 V max at VCC = 4.5 V - provides robust noise margin (>1.3 V)
Power Dissipation	ICC = 8.0 μA (typ), 160 μA (max) at −40 °C to +125 °C - suitable for low-quiescent-power embedded systems
ESD Protection	HBM > 2000 V, CDM > 1000 V - meets industrial handling requirements without external protection

Pinout & Package

TSSOP16 package (SOT403-1): 4.4 mm body width, 0.65 mm lead pitch, 16-terminal surface-mount plastic thin shrink small outline package rated for −40 °C to +125 °C operation.

Pin/Terminal	Circuit Role	Design Meaning
1, 15	1OE, 2OE	Active-low output enable inputs - independently disable 1Y or 2Y to high-impedance state
2, 14	S1, S0	Shared binary select inputs - determine which of four inputs (I0–I3) routes to Y per channel
3–6, 10–13	1I0–1I3, 2I0–2I3	Data input terminals - eight total inputs grouped into two sets of four for independent multiplexing
7, 9	1Y, 2Y	Non-inverting 3-state outputs - drive system bus only when respective OE is LOW
8	GND	Ground reference - return path for all internal logic and I/O currents
16	VCC	Positive supply - powers internal logic and output drivers; clamp diodes referenced to this node

Key Features

Feature	Design Value
Non-inverting data path	Preserves signal polarity across multiplexer - eliminates need for external inversion in timing-critical paths
3-state outputs	Enable direct connection to shared data buses without contention - supports multi-master arbitration
Wide supply range (2.0–6.0 V)	Allows interoperability between 3.3 V microcontrollers and 5 V legacy peripherals without level shifters
Input clamp diodes	Permit safe overvoltage input (e.g., 5 V signals into 3.3 V system) when series resistors limit current to ±20 mA
Latch-up immunity	Exceeds 100 mA per JESD78 Class II Level B - ensures reliability in noisy industrial environments

Applications

Microcontroller Peripheral Multiplexing

Industrial Bus Arbitration

Use Scenario: Selecting among multiple sensor inputs (e.g., ADC channels, GPIO expanders) connected to a single MCU data bus.

IC Role / Device Role / Timing Role: Dual 4:1 data selector routing analog front-end or digital I/O signals to shared MCU interface pins.

Use Value: Reduces MCU pin count by 50% versus discrete routing; enables flexible sensor configuration without PCB redesign.

Use Scenario: Managing access to a shared RS-485 transceiver or CAN controller among multiple processor cores.

IC Role / Device Role / Timing Role: 3-state bus switch enabling time-sliced communication on a common physical layer.

Use Value: Eliminates need for external bus buffers; supports sub-20 ns enable/disable transitions for deterministic arbitration.

Test Equipment Signal Routing

Digital Logic Prototyping

Use Scenario: Dynamically reconfiguring signal paths in automated test fixtures to route DUT outputs to different measurement instruments.

IC Role / Device Role / Timing Role: High-speed multiplexer controlling stimulus/response paths in boundary-scan or functional test systems.

Use Value: Achieves <25 ns propagation delay and <15 ns enable/disable - meets timing closure for 20+ MHz test clock domains.

Use Scenario: Building configurable logic blocks on breadboards or PCBs where fixed-function ICs replace FPGA resources.

IC Role / Device Role / Timing Role: General-purpose data selector implementing combinational logic (e.g., ALU operand selection, register file read ports).

Use Value: Provides verified, production-grade 4:1 mux functionality with guaranteed timing and ESD robustness - no HDL synthesis or place-and-route required.

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
74HCT253PW	TTL-compatible inputs (VIH = 2.0 V min); identical pinout and timing	Better suited for mixed 5 V TTL/CMOS systems; requires VCC = 4.5–5.5 V	Select when interfacing legacy 5 V logic families; not recommended for 3.3 V-only designs
SN74LV253APW	Lower VCC range (2.0–5.5 V); higher drive strength (±12 mA); same pinout	Superior noise immunity at 3.3 V; optimized for LV logic families	Prefer for new 3.3 V designs requiring tighter VOH/VOL margins and faster edge rates

Compared with 74HC253PWHL, 74HCT253PW offers TTL-level input compatibility at the cost of reduced supply flexibility, while SN74LV253APW improves 3.3 V performance and drive but lacks the 6 V tolerance critical for mixed-voltage legacy integration.

FAQ

What is the maximum clock frequency supported by the 74HC253PWHL?

The 74HC253PWHL does not operate on a clock; it is a combinational logic device. Its usable data rate depends on propagation delay and system setup/hold timing. With tpd = 16 ns (typ) at VCC = 6.0 V, it supports reliable data switching up to approximately 30 MHz in well-designed PCB layouts with controlled trace impedance and load capacitance ≤15 pF.

Can 74HC253PWHL interface directly with 3.3 V microcontrollers?

Yes. At VCC = 3.3 V, the 74HC253PWHL guarantees VIH ≥ 2.1 V and VIL ≤ 1.2 V (interpolated from datasheet specs), providing >1.1 V noise margin against standard 3.3 V CMOS logic levels. Its 2.0–6.0 V supply range allows native operation without level shifters.

Is the TSSOP16 package (SOT403-1) RoHS and REACH compliant?

Yes. The 74HC253PWHL in TSSOP16 packaging complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia confirms lead-free terminations, halogen-free molding compound, and full substance declaration per IPC-1752A.

Does the 74HC253PWHL require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs must be tied to VCC or GND to prevent floating states that cause increased ICC and potential oscillation. The device has no internal weak pull-ups/pull-downs; external DC termination is mandatory per JEDEC standards for CMOS logic stability.
