Nexperia USA Inc. 74LV393D-Q100J

Overview

74LV393D-Q100 from Nexperia is an automotive-qualified dual 4-bit binary ripple counter IC with asynchronous master reset (nMR), HIGH-to-LOW edge-triggered clocks (nCP), and buffered Q0–Q3 outputs per counter. It operates from 1.0 V to 3.6 V, supports -40 °C to +125 °C ambient, and delivers 90 MHz max clock frequency at VCC = 3.3 V for timing division in engine control modules.

For engineers reviewing the 74LV393D-Q100 datasheet, 74LV393D-Q100 pinout, 74LV393D-Q100 application, or 74LV393D-Q100 equivalent, this page provides verified functional context, SO14 package mapping, ripple counter timing behavior, AEC-Q100 Grade 1 compliance details, and validated automotive-grade alternatives.

Technical Context

This device implements two independent 4-stage ripple counters using T-type flip-flops cascaded in series, where each stage toggles on the falling edge of its input clock or preceding stage's output. Propagation delay between stages is as low as 4 ns (VCC = 3.3 V, CL = 15 pF), enabling reliable divide-by-16 operation per counter.

The asynchronous nMR inputs clear all four flip-flops simultaneously with sub-13 ns tPHL (VCC = 3.3 V), independent of clock state. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

FAQ

What is the maximum clock frequency supported by the 74LV393D-Q100?

The 74LV393D-Q100 achieves a maximum clock frequency of 90 MHz at VCC = 3.3 V with CL = 15 pF, as specified in Table 7 of the Rev. 4 datasheet. At VCC = 2.7 V, fmax drops to 72 MHz, and at VCC = 2.0 V, it is 53 MHz. These values assume proper PCB layout with decoupling and controlled impedance traces.

Can the two counters operate independently with different clock sources?

Yes - 1CP (Pin 1) and 2CP (Pin 13) are fully isolated clock inputs, allowing independent triggering of each 4-bit counter. The functional diagram (Fig. 3) and pin description (Table 2) confirm no internal coupling; each counter advances only on its own nCP falling edge and resets only via its dedicated nMR input.

Is the 74LV393D-Q100 compatible with 5 V logic inputs?

No - the 74LV393D-Q100 is not 5 V tolerant. Its absolute maximum input voltage is VCC + 0.5 V (Table 4), and VIH is specified up to VCC only (Table 5). For 5 V input compatibility, consider the pin-compatible 74LVC393PW-Q100, which supports inputs up to 5.5 V while maintaining AEC-Q100 Grade 1 qualification.

How does the asynchronous reset affect counter state propagation?

The nMR inputs (Pins 2 and 12) force all Q outputs LOW within 13 ns (tPHL, VCC = 3.3 V), regardless of clock phase or current count value. This immediate, clock-independent clearing is confirmed in Section 1 (General description) and Table 7 (Dynamic characteristics), making it suitable for fail-safe reset in ASIL-B systems.
