Nexperia USA Inc. 74HC253D,653

Overview

74HC253D,653 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) per channel. 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) in SO16 package. Used for data routing in bus-controlled digital systems.

For engineers reviewing the 74HC253D,653 datasheet, 74HC253D,653 pinout, 74HC253D,653 application, or 74HC253D,653 equivalent, key selection factors include dual-channel 4:1 multiplexing capability, TTL-compatible input thresholds (for 74HCT variant), 3-state bus interface readiness, supply voltage flexibility, and SO16 thermal performance at extended temperature.

Technical Context

The device implements two independent 4:1 multiplexers sharing common select inputs (S0, S1), each with four dedicated data inputs (1I0–1I3, 2I0–2I3), one output (1Y, 2Y), and an individual active-low output enable (1OE, 2OE). Outputs enter high-impedance state when respective OE is HIGH.

Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Static characteristics confirm VIH ≥ 3.15 V and VIL ≤ 1.35 V at VCC = 4.5 V (74HC), while dynamic timing specifies tpd = 16 ns (max 45 ns) and ten = 9 ns (max 26 ns) at VCC = 6.0 V.

FAQ

What is the maximum clock frequency supported by the 74HC253D,653?

The 74HC253D,653 does not operate on a clock; it is a combinatorial multiplexer. Its usable data rate is governed by propagation delay (16 ns typical at VCC = 6.0 V) and transition time (4 ns typical), supporting signal switching up to approximately 30 MHz under ideal load conditions. Maximum reliable toggle rate depends on output load capacitance and drive strength.

Can 74HC253D,653 be used with 3.3 V microcontrollers?

Yes. The 74HC253D,653 operates down to 2.0 V and is fully compatible with 3.3 V systems. At VCC = 3.3 V, VIH is guaranteed ≥ 2.1 V and VIL ≤ 1.2 V, ensuring reliable recognition of standard 3.3 V logic levels. Output VOH exceeds 3.0 V at IO = –4 mA, meeting 3.3 V CMOS input requirements.

Does the SO16 package require thermal pad soldering?

No. The SO16 (SOT109-1) package used for 74HC253D,653 has no exposed thermal pad. Thermal dissipation relies on leads and PCB copper; no special thermal land or soldering is needed. Derating begins linearly at 12.4 mW/K above 110 °C ambient, with Ptot = 500 mW at ≤110 °C.

How does the 3-state output behave during power-up?

During power-up, outputs default to high-impedance if VCC rises before valid logic is applied to OE pins. However, because OE is active-low, floating OE pins may cause unintended output activation. Best practice is to tie 1OE and 2OE to VCC via pull-up resistors (e.g., 10 kΩ) to ensure outputs remain disabled until firmware asserts control.
