Nexperia USA Inc. 74LVC823APW,118

Overview

74LVC823APW,118 from Nexperia is a 9-bit positive-edge-triggered D-type flip-flop with independent clock enable (CE), master reset (MR), and 3-state outputs (Q0–Q8), operating from 1.2 V to 3.6 V supply. It features 5 V tolerant inputs/outputs, supports mixed-voltage bus interfacing (3.3 V core ↔ 5 V peripherals), and delivers ≤10.0 ns propagation delay at 3.6 V - used in industrial control backplanes and memory address latching.

For engineers reviewing the 74LVC823APW,118 datasheet, 74LVC823APW,118 pinout, 74LVC823APW,118 application, or 74LVC823APW,118 equivalent, this device is selected for high-density synchronous data capture where voltage translation, low static current (<40 μA), and precise timing control (tsu = 1.3 ns, th = 1.3 ns @ 3.6 V) are critical in space-constrained TSSOP24 layouts.

Technical Context

This device implements nine independent edge-triggered D flip-flops sharing one common clock (CP), with asynchronous active-low MR and separate active-low OE controlling 3-state output buffers. Register and output buffer operations are decoupled: OE toggling does not affect stored state, enabling glitch-free bus sharing.

Its CMOS architecture complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), and supports full 5.5 V tolerance on I/O pins when disabled - allowing safe interfacing between 3.3 V logic domains and legacy 5 V systems without level shifters.

FAQ

Can 74LVC823APW,118 operate reliably at 1.2 V supply?

Yes - the device is fully characterized down to 1.2 V per JEDEC JESD8-C, with guaranteed functionality including tsu/th ≥3.0 ns and tpd ≤20 ns at that voltage. Static current remains below 10 μA, making it suitable for battery-backed or ultra-low-power industrial sensors.

What happens to Qn outputs when OE is HIGH and VCC = 0 V?

When VCC = 0 V and OE = HIGH, outputs enter high-impedance state with IOFF ≤ ±20 μA (measured at VI/VO = 5.5 V), preventing back-driving of upstream 5 V buses - a key requirement for hot-swap and power sequencing safety in modular systems.

Is the TSSOP24 package (SOT355-1) lead-free and RoHS compliant?

Yes - the 74LVC823APW,118 uses a lead-free, halogen-free, RoHS-compliant TSSOP24 package per Nexperia's product compliance documentation (document ID: "Nexperia_RoHS_Compliance_74LVC823A"). Reflow profile follows JEDEC J-STD-020E for MSL3 handling.

How does MR interact with CE and CP during reset assertion?

MR is asynchronous and dominant: asserting MR LOW forces all Qn outputs LOW immediately, irrespective of CE state or CP edge timing. The internal flip-flop states are reset concurrently, and CE/CP activity is ignored until MR returns HIGH - ensuring deterministic initialization in safety-critical sequences.
