Nexperia USA Inc. 74LV393PW,118

Overview

74LV393PW,118 from Nexperia is a dual 4-bit binary ripple counter IC with asynchronous master reset per counter, operating from 1.0 V to 3.6 V supply, featuring HIGH-to-LOW edge-triggered clocks (1CP/2CP), independent 4-bit outputs (1Q0–1Q3 and 2Q0–2Q3), and guaranteed operation from −40 °C to +125 °C in TSSOP14 package - used for clock division, frequency synthesis, and timing control in industrial logic systems.

For engineers reviewing the 74LV393PW,118 datasheet, 74LV393PW,118 pinout, 74LV393PW,118 application, or 74LV393PW,118 equivalent, this page delivers verified functional architecture, validated timing parameters (e.g., tpd = 5 ns @ 3.3 V), real-world ripple counter behavior, and precise TSSOP14 terminal mapping - all critical for synchronous design integration and low-voltage logic compatibility verification.

Technical Context

The 74LV393PW,118 implements two independent 4-stage ripple counters using cascaded T-type flip-flops, where each stage advances on the HIGH-to-LOW transition of its dedicated clock input (1CP or 2CP). Reset is fully asynchronous and active-HIGH (1MR/2MR), forcing all four outputs LOW regardless of clock state.

It supports TTL-level inputs at VCC ≥ 2.7 V, includes input clamp diodes enabling overvoltage-tolerant interfacing via current-limiting resistors, and delivers rail-to-rail output swing (VOH ≥ 2.2 V, VOL ≤ 0.5 V @ 3.0 V, IO = ±6 mA) with propagation delays as low as 5 ns (tpd, typical @ 3.3 V, CL = 15 pF).

FAQ

Can the 74LV393PW,118 be operated at 1.2 V with full timing guarantees?

Yes. The datasheet specifies guaranteed operation down to 1.0 V, including propagation delay (tpd ≤ 75 ns @ 1.2 V), output drive (VOL ≤ 0.4 V @ 6 mA), and input thresholds (VIH = 0.9 V, VIL = 0.3 V). All static and dynamic parameters are characterized across the full 1.0 V to 3.6 V range, with no derating required at 1.2 V.

Is there internal synchronization between the two counters' clock inputs?

No. The 74LV393PW,118 contains two fully independent ripple counters with separate clock (1CP/2CP) and reset (1MR/2MR) terminals. There is no internal clock synchronization or carry signal between them - each operates autonomously, allowing asynchronous or phase-offset timing functions.

What is the maximum capacitive load the outputs can drive reliably?

The outputs are specified for CL = 50 pF in dynamic testing, with tpd and fmax data provided at CL = 15 pF and CL = 50 pF. Driving loads >50 pF increases propagation delay and may reduce maximum frequency; for >100 pF, external buffering is recommended to maintain timing integrity and output voltage margins.

Does the 74LV393PW,118 support hot insertion or live swapping?

No. The device lacks hot-swap protection circuitry such as power-on reset, I_OFF isolation, or back-drive immunity. Applying VCC while inputs are biased violates the absolute maximum rating for input clamping current (±20 mA), risking permanent damage. Power sequencing must follow VCC-first, signal-later protocol.
