NXP Semiconductors 74HC75PW,118

Overview

74HC75PW,118 from Nexperia is a quad bistable transparent latch IC with complementary Q/nQ outputs, two independent enable inputs (LE12 for latches 1–2, LE34 for latches 3–4), 2.0 V to 6.0 V supply range, and operation up to +125 °C - used in digital bus interfacing, data sampling, and address/data latching in industrial microcontroller systems.

For engineers reviewing the 74HC75PW,118 datasheet, 74HC75PW,118 pinout, 74HC75PW,118 application, or 74HC75PW,118 equivalent, this page delivers verified functional behavior, TSSOP16 package layout, propagation delay (10–32 ns), set-up/hold timing, and direct substitution guidance against industry-standard HC-family latches.

Technical Context

The 74HC75PW implements four independent transparent latches arranged as two pairs sharing active-HIGH enable signals: LE12 controls latches 1 and 2, while LE34 controls latches 3 and 4. Each latch features true and complementary outputs (nQ and nQ), enabling direct connection to differential receivers or logic-level inversion without external inverters.

Its CMOS architecture ensures low static current (≤160 µA at VCC = 6.0 V, −40 °C to +125 °C), high noise immunity, and input clamping diodes supporting interface to voltages exceeding VCC when used with current-limiting resistors - critical for mixed-voltage system interfacing.

FAQ

What is the maximum clock frequency supported by the 74HC75PW,118?

The 74HC75PW,118 is not a clocked device - it is a transparent latch controlled by enable signals (LE12/LE34), not a clock input. Its effective data throughput depends on enable pulse width (minimum 14 ns at 6 V) and propagation delay (as low as 10 ns). It does not specify or operate at a "clock frequency" like flip-flops; instead, it responds asynchronously to enable transitions with defined setup/hold timing.

Can the 74HC75PW,118 be used with a 3.3 V supply?

Yes - the 74HC75PW,118 is fully specified for 3.3 V operation (within its 2.0 V to 6.0 V range). At VCC = 3.3 V, VIH is guaranteed ≥2.31 V and VIL ≤1.0 V (per JEDEC JESD8C), and output drive meets ±4 mA with VOL ≤0.26 V and VOH ≥2.97 V, ensuring reliable interfacing with 3.3 V microcontrollers and peripherals.

Are the complementary outputs (Q and Q) truly inverted, or do they exhibit skew?

Yes - the Q and Q outputs are actively complementary: when Q is HIGH, Q is LOW, and vice versa. Measured transition times (tt) show matched rise/fall characteristics (6–19 ns, depending on VCC and temperature), with typical skew <1 ns between Q/Q edges under matched loading - confirmed by functional diagram Fig. 4 and dynamic characterization in Table 7.

Does the 74HC75PW,118 include ESD protection, and what level is certified?

Yes - the 74HC75PW,118 includes on-chip ESD protection rated per JEDEC standards: Human Body Model (HBM) >2000 V (Class 2) and Charged Device Model (CDM) >1000 V (Class C3). This is implemented via internal clamp diodes on all inputs and outputs, enabling robust handling during board assembly and field operation without external protection components.
