Nexperia USA Inc. 74LV4094D,118

Overview

74LV4094D,118 from Nexperia is an 8-bit serial-in/serial-or-parallel-out shift-and-store bus register with independent shift and storage clocks, 3-state outputs, and dual serial outputs (QS1/QS2) for daisy-chain cascading. It operates from 1.0 V to 3.6 V, supports TTL-level inputs at VCC ≥ 2.7 V, and functions across –40 °C to +125 °C - used in LED matrix drivers and remote I/O expansion where low-voltage serial-to-parallel conversion is required.

For engineers reviewing the 74LV4094D,118 datasheet, 74LV4094D,118 pinout, 74LV4094D,118 application, or 74LV4094D,118 equivalent, key selection factors include its dual-edge-cascadable serial outputs (QS1 on CP↑, QS2 on CP↓), strobe-controlled parallel latch timing, 3-state output enable (OE), wide VCC range (1.0–3.6 V), and SO16 package compatibility with industrial temperature operation.

Technical Context

The device implements two synchronized but independent 8-stage registers: a shift register clocked on CP rising edges and a storage register loaded on STR high assertion. Data propagates through the shift register on each CP↑, while QS1 mirrors Q6S (stage 6 output) on CP↑ and QS2 mirrors Q7S (stage 7 output) on CP↓ - enabling robust inter-device synchronization under varying clock edge slew rates.

Its 3-state outputs are controlled solely by OE (active-HIGH), with no effect on internal register states. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors, and the design complies with JESD8-7/8-5/8C voltage standards and exceeds JESD78 Class II Level B latch-up immunity (>100 mA).

FAQ

What is the minimum supply voltage for guaranteed operation of the 74LV4094D,118?

The 74LV4094D,118 is fully specified and functional down to 1.0 V, with static characteristics guaranteed from 1.2 V and operational behavior validated to 1.0 V (inputs referenced to GND or VCC). At 1.0 V, propagation delays increase and maximum frequency decreases, but logic functionality remains intact - critical for ultra-low-power battery applications.

How do QS1 and QS2 differ in timing behavior and use case?

QS1 outputs the data from shift register stage 6 on every CP rising edge, enabling tight-timing cascading in high-speed systems. QS2 outputs stage 7 data on the subsequent CP falling edge, providing extra setup time for downstream devices - this dual-output scheme accommodates both fast (QS1) and slow (QS2) clock edge conditions within the same chain without added delay elements.

Can the 74LV4094D,118 interface directly with 5 V TTL outputs?

Yes - when VCC is set to 2.7 V or higher, the 74LV4094D,118 accepts TTL input levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V). A 5 V TTL output driving D or CP will meet these thresholds directly. For VCC < 2.7 V, external level-shifting or resistor-divider networks are required to avoid violating input voltage limits.

Is the strobe (STR) input edge-sensitive or level-sensitive?

The STR input is level-sensitive: data transfers from the shift register to the storage register while STR is held HIGH. The transfer occurs synchronously with the next CP rising edge after STR goes HIGH - meaning STR must be asserted before the intended CP edge and remain HIGH until the transfer completes. This ensures deterministic latch timing aligned to the system clock.
