Product details
Overview
N74F253D,602 from NXP Semiconductors (formerly Philips) is a dual 4-input multiplexer with 3-state outputs, designed for bus-oriented data routing in TTL-compatible digital systems. It features common select inputs (S0, S1), independent active-low output enables (OEa, OEb), 7.0 ns typical propagation delay, 12 mA typical supply current, and operates at 5 V ±10% over 0°C to +70°C.
For engineers reviewing the N74F253D,602 datasheet, N74F253D,602 pinout, N74F253D,602 application, or N74F253D,602 equivalent, key selection considerations include 3-state bus interface capability, dual-channel independent enable control, propagation timing across data and select paths, and SO16 package compatibility with legacy 74F logic layouts.
Technical Context
The N74F253D,602 implements two independent 4:1 multiplexers sharing S0/S1 select lines but with separate OEa/OEb controls-enabling selective channel gating without inter-channel crosstalk. Each multiplexer routes one of four input signals (I0–I3) to its respective 3-state output (Ya/Yb) based on binary select encoding.
Its 3-state outputs support wired-OR bus architectures when multiple devices share a common data line, provided only one OE is asserted low at any time. Input loading is standardized at 1.0 FAST unit load (20 µA/0.6 mA), and output drive capability is rated at –3 mA (IOH) and 24 mA (IOL) under recommended conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL systems and tolerates ±10% rail variation |
| Propagation Delay (In→Y) | 7.0 ns typical - defines maximum data path latency for timing-critical address/data switching |
| Output Enable Time | 8.0 ns max - determines minimum interval between OE assertion and valid output level establishment |
| Output Drive (IOL) | 24 mA - supports direct fan-out to ≥10 standard TTL loads without buffering |
| Input Loading | 1.0 FAST unit load - simplifies bus loading calculations and ensures predictable signal integrity |
| Operating Temperature | 0°C to +70°C - qualifies for commercial-grade embedded control and instrumentation applications |
Pinout & Package
Package: SO16 (plastic small outline, 16-lead, 3.9 mm body width, SOT109-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | I0a, I1a, I2a, I3a | Port A data inputs - four independent logic sources selectable by S0/S1 for Ya output |
| 5, 6, 7, 9 | I0b, I1b, I2b, I3b | Port B data inputs - second set of four sources routed to Yb under same S0/S1 control |
| 8 | GND | Ground reference - common return for all internal logic and output drivers |
| 10, 11 | OEa, OEb | Active-low output enables - independently disable Ya/Yb into high-impedance state for bus sharing |
| 12, 13 | S1, S0 | Common select inputs - binary-encoded address (S1S0 = 00–11) selects which Ix drives output |
| 14, 15 | Ya, Yb | 3-state outputs - present selected input or Hi-Z depending on OE state and select code |
| 16 | VCC | Positive supply - powers all logic and output stages; requires local 0.1 µF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 4:1 mux channels | Enables simultaneous routing of two separate 4-source data streams using shared select logic |
| Separate active-low OE inputs | Allows per-channel bus arbitration without requiring external gating logic or timing coordination |
| 3-state outputs with 24 mA sink capability | Permits direct connection to shared data buses while maintaining signal integrity and load margin |
| 7.0 ns typical propagation delay | Supports operation in 100+ MHz system clock domains when used in non-critical timing paths |
Applications
| Microprocessor Address Decoding | Test Equipment Signal Routing |
|---|---|
Use Scenario: Selecting between multiple peripheral address ranges in an 8-bit microcontroller system with limited address lines. IC Role / Device Role / Timing Role: Dual-channel address decoder that maps I/O space using S0/S1 while isolating unused peripherals via OEa/OEb. Use Value: Reduces glue logic count by consolidating two decode functions into one SO16 package with no external enable logic required. | Use Scenario: Dynamically reconfiguring signal paths between DUT, stimulus generator, and measurement instruments in automated test fixtures. IC Role / Device Role / Timing Role: Bidirectional analog/digital signal switch enabling flexible test topology changes under microcontroller control.

IC Role / Device Role / Timing Role: Bus interface multiplexer providing controlled, non-conflicting access to shared data lines using 3-state outputs. Use Value: Prevents bus contention through hardware-enforced single-driver arbitration, eliminating risk of latch-up or excessive current draw. | Use Scenario: Interfacing modern FPGA-based controllers with legacy 74F-series logic subsystems requiring precise voltage and timing alignment. IC Role / Device Role / Timing Role: Level- and timing-transparent bridge component matching 74F AC/DC characteristics for seamless integration. Use Value: Maintains system timing budgets and noise margins without requiring redesign of existing PCB traces or termination schemes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-input multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74F253N | DIP-16 package; identical electrical specs and pinout; higher thermal resistance and larger footprint | Preferred for prototyping, through-hole assembly, or legacy board rework where SO16 reflow is unavailable | Select when manual soldering, socketing, or compatibility with existing DIP-based test fixtures is required |
| 74ACT253M | Advanced CMOS process; 3.3 V/5 V tolerant inputs; 5.5 ns max tPLH; lower ICC (4 mA typ); different DC thresholds (VIH = 2.0 V min) | Better suited for mixed-voltage systems and lower-power designs; not drop-in due to VIH/VIL mismatch with 74F | Choose for new designs targeting reduced power or 3.3 V interface compatibility, but verify input threshold margins |
Compared with SN74F253N and 74ACT253M, the N74F253D,602 provides optimal fit for volume SO16-based commercial systems requiring strict 74F timing, loading, and 5 V operation-without layout change or logic-level adaptation.

FAQ
What is the operating voltage range for the N74F253D,602?
The N74F253D,602 operates within a supply voltage range of 4.5 V to 5.5 V, fully compliant with standard 5 V TTL specifications. This range accommodates ±10% tolerance on nominal 5 V rails and ensures stable functionality across commercial temperature conditions (0°C to +70°C). The N74F253D,602 does not support 3.3 V operation or wider voltage excursions beyond the absolute maximum rating of –0.5 V to +7.0 V.
Does the N74F253D,602 support simultaneous activation of both output enables?
No-the N74F253D,602 allows independent control of OEa and OEb, but simultaneous low assertion is electrically permissible only if Ya and Yb drive separate, isolated loads. When connecting both outputs to a shared bus, only one OE should be active low at a time to prevent contention and exceedance of output current limits. The N74F253D,602 datasheet explicitly warns against tying 3-state outputs together unless all but one device is in Hi-Z.
What is the function of pins 12 and 13 on the N74F253D,602?
Pins 12 and 13 on the N74F253D,602 are S1 and S0 respectively-the common select inputs that determine which of the four data inputs (I0–I3) is routed to each output (Ya and Yb). Their binary combination (S1S0 = 00, 01, 10, 11) selects I0a/I0b, I1a/I1b, I2a/I2b, or I3a/I3b. These pins accept standard TTL logic levels and exhibit 1.0 FAST unit load, ensuring predictable timing and fan-out behavior in cascaded logic networks.
Can the N74F253D,602 be used in place of the SN74LS253?
The N74F253D,602 is not a direct replacement for SN74LS253 due to differences in speed, drive strength, and input thresholds. While both are dual 4:1 multiplexers with 3-state outputs, the N74F253D,602 offers faster propagation (7.0 ns vs. ~15 ns), higher output drive (24 mA vs. 8 mA), and tighter VIH/VIL specs. Substituting N74F253D,602 into an LS-designed circuit may cause timing violations or excessive current draw if load capacitance or termination is unadjusted.
What package type is used for the N74F253D,602?
The N74F253D,602 uses the SO16 plastic small outline package (SOT109-1), featuring 16 leads, 3.9 mm body width, and gull-wing surface-mount terminals. This package is RoHS-compliant, compatible with standard reflow profiles, and pin-for-pin identical to the DIP version (N74F253N) except for lead form and thermal characteristics. The N74F253D,602's SO16 footprint supports high-density PCB layouts and automated assembly processes.
