Nexperia USA Inc. 74HC4094PW-Q100J

Overview

74HC4094PW-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit serial-in/parallel-out shift-and-store bus register with independent shift and storage clocks, 3-state outputs, dual serial outputs (QS1/QS2) for daisy-chaining, and operation from -40 °C to +125 °C. It enables serial-to-parallel data conversion in automotive body control modules requiring robust timing, low-power CMOS logic, and high-noise immunity.

For engineers reviewing the 74HC4094PW-Q100 datasheet, 74HC4094PW-Q100 pinout, 74HC4094PW-Q100 application, or 74HC4094PW-Q100 equivalent, key selection criteria include propagation delay (18 ns typ @ 4.5 V), output enable timing (20 ns enable / 15 ns disable), QS1/QS2 phase alignment for cascaded clocking, and TSSOP16 thermal derating (8.5 mW/K above 91 °C).

Technical Context

This device implements a two-stage pipeline: an 8-bit shift register clocked on CP rising edges, followed by an 8-bit storage latch triggered by STR high. Data appears at QS1 on the same CP↑ edge and at QS2 on the subsequent CP↓ edge-enabling flexible inter-device synchronization across varying clock edge rates.

The 3-state parallel outputs (QP0–QP7) are controlled solely by OE, with no effect on internal register states. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors, supporting mixed-voltage system integration.

FAQ

What is the maximum clock frequency supported by the 74HC4094PW-Q100?

The device supports up to 35 MHz maximum clock frequency at VCC = 6.0 V and CL = 50 pF. At the recommended 4.5 V supply, fmax is 30 MHz. These values assume proper load capacitance and signal integrity; actual achievable rate depends on PCB routing, termination, and fanout.

How do QS1 and QS2 differ in timing behavior?

QS1 outputs the QP7 bit on the same CP rising edge that loads it into the final shift stage. QS2 outputs the same bit on the subsequent CP falling edge. This allows cascading with either fast-clock (QS1) or slow-clock (QS2) synchronization, accommodating varied inter-device propagation delays.

Can the 74HC4094PW-Q100 drive LEDs directly?

Yes - each QP output sources or sinks up to 4.0 mA at 4.5 V VCC with VOL ≤ 0.26 V and VOH ≥ 3.98 V. This is sufficient for low-current indicator LEDs (e.g., 2 mA @ 1.8 V VF). For higher-current or high-brightness LEDs, external drivers are recommended.

Is the TSSOP16 package RoHS and REACH compliant?

Yes - the SOT403-1 (TSSOP16) package used for 74HC4094PW-Q100 is fully RoHS Directive 2011/65/EU compliant and meets REACH SVHC requirements. Lead finish is matte tin, and the material composition is documented in Nexperia's official compliance statements.
