Nexperia USA Inc. 74HC253D-Q100,118

Overview

74HC253D-Q100 from Nexperia is an automotive-qualified dual 4-input CMOS multiplexer with independent 3-state outputs, shared select lines (S0/S1), separate output enable inputs (1OE/2OE), and operation across 2.0 V to 6.0 V supply. It routes one of four binary inputs per channel to its respective output (1Y/2Y) and supports high-impedance bus interfacing in automotive body control modules.

For engineers reviewing the 74HC253D-Q100 datasheet, 74HC253D-Q100 pinout, 74HC253D-Q100 application, or 74HC253D-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, -40 °C to +125 °C operating range, propagation delay ≤35 ns at 4.5 V, 3-state output drive capability, and SO16 package compatibility with legacy PCB footprints.

Technical Context

This device implements two independent 4:1 multiplexers sharing S0 and S1 select inputs but featuring separate output enable controls (1OE, 2OE), enabling selective channel gating without affecting the other path. Each multiplexer has non-inverting data flow and TTL-compatible input thresholds only in the 74HCT variant - the 74HC253D-Q100 uses CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V).

Its 3-state outputs interface directly with system buses, while internal clamp diodes allow safe interfacing with voltages exceeding VCC when used with current-limiting resistors. The logic function adheres to standard Boolean multiplexing: Y = I0·S̄₀S̄₁ + I1·S̄₀S₁ + I2·S₀S̄₁ + I3·S₀S₁, with output disabled (Z) when OE = HIGH.

FAQ

What is the maximum clock frequency supported by the 74HC253D-Q100?

The 74HC253D-Q100 does not operate on a clock signal - it is a combinational logic device. Its usable data rate depends on propagation delay: at VCC = 4.5 V and CL = 15 pF, tpd = 20 ns typ., supporting reliable switching up to ~25 MHz for clean digital waveforms with adequate setup/hold margins.

Can 74HC253D-Q100 interface with 3.3 V microcontrollers while powered at 5 V?

Yes - its CMOS inputs tolerate VIH ≥ 3.15 V at VCC = 4.5 V, making them compatible with 3.3 V logic HIGH levels. However, outputs swing rail-to-rail (0 V to 5 V), so level-shifting is required before connecting to 3.3 V MCU inputs to avoid damage or overstress.

Does the SO16 package (SOT109-1) support automatic optical inspection (AOI)?

No - only the DHVQFN16 package (SOT763-1) features side-wettable flanks for AOI. The SO16 package relies on X-ray or electrical test for solder joint verification; its gull-wing leads require traditional vision-based inspection with appropriate lighting and contrast settings.

How does the 74HC253D-Q100 handle input signals exceeding VCC?

Internal input clamp diodes allow safe operation with inputs up to VCC + 0.5 V when used with series current-limiting resistors (e.g., 1 kΩ). This enables robust interfacing with higher-voltage sensors or legacy 5 V signals in 3.3 V systems without external protection circuitry.
