Nexperia USA Inc. 74LVC823APW,112

Overview

74LVC823APW,112 from Nexperia is a 9-bit positive edge-triggered D-type flip-flop with 3-state outputs, 5 V tolerant I/O, common clock (CP), master reset (MR), clock enable (CE), and output enable (OE). It operates from 1.2 V to 3.6 V supply, supports -40 °C to +125 °C ambient, and functions as a bus-oriented register in mixed-voltage digital systems.

For engineers reviewing the 74LVC823APW,112 datasheet, 74LVC823APW,112 pinout, 74LVC823APW,112 application, or 74LVC823APW,112 equivalent, key selection criteria include 5 V tolerance on all I/O pins, 9-bit synchronous storage with independent 3-state control, propagation delay down to 1.5 ns at 3.3 V, and TSSOP24 packaging for high-density PCB layouts.

Technical Context

This device implements nine independent D-type latches triggered on the LOW-to-HIGH transition of CP, with data capture conditioned by CE = LOW and set-up/hold timing compliance. MR provides asynchronous active-LOW global reset, while OE enables/disables all Qn outputs without affecting internal register state.

Its 5 V tolerant inputs and outputs allow direct interfacing between 3.3 V logic domains and legacy 5 V buses, and its flow-through pinout (D0–D8 left side, Q0–Q8 right side) minimizes trace routing complexity in bus applications. The design complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36 across voltage ranges.

FAQ

What is the maximum clock frequency supported by the 74LVC823APW,112?

The 74LVC823APW,112 supports a maximum clock frequency of 120 MHz at VCC = 3.0–3.6 V and -40 °C to +125 °C ambient. At 3.3 V and 25 °C, typical fmax reaches 200 MHz. This is determined by the minimum CP pulse width (3.3 ns) and propagation delay limits specified in Table 7 of the datasheet.

Can the 74LVC823APW,112 safely interface with a 5 V microcontroller while powered from 3.3 V?

Yes - all inputs and outputs are rated for 5.5 V absolute maximum and fully 5 V tolerant per JEDEC JESD8-7A/5A/C standards. When VCC = 3.3 V, VIH(min) = 2.0 V and VOH(min) = 2.2 V at 24 mA, ensuring reliable TTL and 5 V CMOS compatibility without external circuitry.

How does the master reset (MR) interact with the clock enable (CE) and output enable (OE) functions?

MR is asynchronous and overrides all other controls: when asserted LOW, it forces all Qn outputs to LOW immediately, regardless of CE or OE state. CE affects only data capture (holding register state when HIGH), while OE affects only output driver state (high-Z when HIGH) - neither influences MR's reset action.

Is the exposed thermal pad on the TSSOP24 package electrically connected or required to be soldered?

No - the exposed pad on SOT355-1 (TSSOP24) is not electrically connected and has no mechanical or electrical requirement for soldering. If soldered, the land must remain floating or be connected to GND; it serves only thermal enhancement and does not form part of the signal or power path.
