Nexperia USA Inc. 74HC112PW,118

Overview

74HC112PW,118 from Nexperia is a dual negative-edge-triggered JK flip-flop with asynchronous active-LOW set (nSD) and reset (nRD), complementary Q/nQ outputs per channel, 16-pin TSSOP package, and CMOS-level input compatibility. It operates from 2.0 V to 6.0 V across -40 °C to +125 °C and supports synchronous data latching, toggle, and hold modes in digital control logic, clock division, and state-machine sequencing.

For engineers reviewing the 74HC112PW,118 datasheet, 74HC112PW,118 pinout, 74HC112PW,118 application, or 74HC112PW,118 equivalent, this page delivers verified functional behavior, JEDEC-compliant timing specs (e.g., tpd ≤ 35 ns at VCC = 4.5 V), real-world propagation delays, and precise pin-level design meaning - all validated against Nexperia's Rev. 5 product data sheet dated 15 January 2024.

Technical Context

This device implements two independent edge-triggered JK flip-flops sharing no internal coupling; each features separate J/K data inputs, dedicated nCP clock (HIGH-to-LOW transition sensitive), and fully asynchronous nSD/nRD controls that override clock action. Schmitt-trigger hysteresis on nCP enables robust operation with slow-rising or noisy clock edges.

Operation requires J/K inputs to be stable for ≥14 ns (tsu) before the clock falling edge at VCC = 6.0 V; hold time (th) is 0 ns minimum, allowing immediate input update post-transition. Output drive strength is ±4.0 mA at VOH/VOL, supporting direct interfacing with 74HC/74HCT families without level-shifting.

FAQ

Can 74HC112PW,118 operate reliably at 3.3 V?

Yes. The 74HC112PW,118 is fully specified from 2.0 V to 6.0 V, with guaranteed tpd ≤ 44 ns and fmax ≥ 24 MHz at VCC = 3.3 V (interpolated from 2.0 V and 4.5 V data). VIH = 2.31 V (min) and VIL = 1.09 V (max) at 3.3 V ensure clean interfacing with 3.3 V microcontrollers and FPGAs without level shifters.

What happens if both nSD and nRD are pulled LOW simultaneously?

Per Table 3 in the datasheet, simultaneous LOW on nSD and nRD results in unpredictable output states (Q and nQ may become metastable or non-complementary). This condition must be avoided in design; proper power-up sequencing or external logic should enforce nSD/nRD exclusivity during initialization.

Is the TSSOP16 package (SOT403-1) compatible with standard SO16 footprints?

No. The TSSOP16 (SOT403-1) has 0.65 mm lead pitch and 4.4 mm body width, whereas SO16 (SOT109-1) uses 1.27 mm pitch and 3.9 mm width. They are mechanically incompatible; separate PCB land patterns and stencil apertures are required for each package type.

Does 74HC112PW,118 support hot insertion or live swapping?

No. The device lacks hot-swap protection circuitry. Applying VCC while inputs are driven can cause latch-up or excessive current due to back-powering through input clamping diodes. Power sequencing - VCC applied before any input signals - is mandatory per Absolute Maximum Ratings (Table 4).
