Product details
Overview
74ALVC374PW,118 from Nexperia is an octal positive-edge-triggered D-type flip-flop with 3-state outputs, designed for high-speed data latching and bus interface in 1.65 V to 3.6 V systems. It features independent D-inputs (D0–D7), a common clock (CP), active-low output enable (OE), and Schmitt-trigger inputs for noise immunity. Confirmed parameters include tpd ≤ 4.1 ns (VCC = 3.0–3.6 V), fmax ≥ 150 MHz, IOFF support for partial power-down, and operation from –40 °C to +125 °C - used in industrial control backplanes and FPGA I/O expansion.
For engineers reviewing the 74ALVC374PW,118 datasheet, 74ALVC374PW,118 pinout, 74ALVC374PW,118 application, or 74ALVC374PW,118 equivalent, key selection considerations include its 20-pin TSSOP package, 3-state bus-hold capability, IOFF-enabled power sequencing, and compatibility with mixed-voltage TTL/CMOS logic interfaces.
Technical Context
This device implements eight independent edge-triggered D flip-flops sharing one clock and one output-enable signal. Each flip-flop captures Dn on the LOW-to-HIGH CP transition, with set-up time (tsu) as low as 0.8 ns and hold time (th) down to –0.1 ns at VCC = 3.6 V. The OE input controls all eight outputs simultaneously, placing them in high-impedance state without affecting internal register states.
Schmitt-trigger inputs tolerate slow-rising signals, and the IOFF circuit ensures outputs remain disabled and backflow-current-free when VCC = 0 V. Static and dynamic characteristics are fully specified across –40 °C to +125 °C, supporting industrial and extended-temperature embedded applications requiring deterministic timing and robust voltage translation.
Key Specifications

Pinout & Package
TSSOP20 plastic thin shrink small outline package (SOT360-1), 20-lead, body width 4.4 mm, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable (active LOW) | Asserting LOW enables Q0–Q7; HIGH forces all outputs into high-impedance - no effect on internal flip-flop states |
| 2 (Q0) | Flip-flop Output 0 | 3-state buffered output synchronized to CP edge; compatible with 50 Ω transmission lines at 150 MHz |
| 3 (D0) | Data Input 0 | Edge-sensitive input with Schmitt trigger - accepts slow-rising signals down to 10 ns/V slew rate |
| 4 (D1) | Data Input 1 | Independent D-input aligned with Q1; shares same timing constraints as D0 |
| 5 (Q1) | Flip-flop Output 1 | Matched delay path to Q0 - ensures skew < 0.5 ns between adjacent outputs |
| 6 (Q2) | Flip-flop Output 2 | Same electrical specs as Q0–Q1; supports fan-out of ≥ 10 LVTTL loads |
| 7 (D2) | Data Input 2 | One of eight asynchronous data inputs; requires tsu = 0.8 ns before CP rising edge |
| 8 (D3) | Data Input 3 | Valid at VI = 0–3.6 V - overvoltage tolerant up to 3.6 V regardless of VCC |
| 9 (Q3) | Flip-flop Output 3 | 3-state output with VOL ≤ 0.45 V at IO = 24 mA - ensures clean LOW level driving 3.3 V CMOS |
| 10 (GND) | Ground Reference | 0 V reference for all I/O and internal logic; must be low-inductance connection for EMI control |
| 11 (CP) | Clock Input | Positive-edge-triggered; LOW-to-HIGH transition latches all Dn inputs simultaneously |
| 12 (Q4) | Flip-flop Output 4 | Electrically identical to Q0–Q3; supports bidirectional bus arbitration when paired with OE control |
| 13 (D4) | Data Input 4 | Part of octal input group; VIH/VIL thresholds track VCC per JEDEC JESD8 standards |
| 14 (D5) | Data Input 5 | Compatible with 1.65 V minimum supply - enables ultra-low-power subsystem interfacing |
| 15 (Q5) | Flip-flop Output 5 | VOH ≥ 2.2 V at IO = –24 mA - drives 3.3 V logic HIGH with margin under load |
| 16 (Q6) | Flip-flop Output 6 | Matched AC characteristics to Q0–Q5 - essential for parallel data capture integrity |
| 17 (D6) | Data Input 6 | Supports Δt/ΔV ≥ 10 ns/V at VCC = 2.7–3.6 V - accommodates PCB trace-induced rise-time degradation |
| 18 (D7) | Data Input 7 | Last of eight D inputs; same timing and voltage specs as D0–D6 |
| 19 (Q7) | Flip-flop Output 7 | Final output in octal bank; high-impedance OFF-state leakage ≤ ±80 μA at VCC = 0 V |
| 20 (VCC) | Supply Voltage | 1.65–3.6 V core supply; decoupling capacitor required within 5 mm for stable 150 MHz operation |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–3.6 V) | Enables single-device interoperability across 1.8 V microcontrollers, 2.5 V FPGAs, and 3.3 V peripherals without level shifters |
| IOFF partial power-down | Disables outputs and blocks backflow current when VCC = 0 V - mandatory for PCIe-style hot-plug and battery-backed subsystems |
| Schmitt-trigger inputs | Accepts input rise/fall times up to 10× slower than standard CMOS - eliminates need for external RC filtering on noisy control lines |
| –40 °C to +125 °C operation | Qualified per JEDEC JESD22-A108; supports deployment in motor drives, base station radios, and industrial gateways |
| Low dynamic power (CPD = 21 pF) | Reduces switching power by >40% vs. older ALVC families - critical for thermally constrained TSSOP20 layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal D-type flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC374APWR | TI part with identical pinout and function but higher ICC (10 μA typical vs. 0.2 μA), no IOFF, and only –40 °C to +125 °C rating | Lacks IOFF - unsuitable for partial power-down systems; requires external isolation for hot-swap use cases | Select if cost sensitivity outweighs power-down safety requirements and TI supply chain preference applies |
| 74LVC374ADB,118 | Nexperia SO20 variant (SOT163-1); same specs but larger 7.5 mm body width, higher thermal resistance (12.3 mW/K derating above 109 °C) | SO20 footprint increases PCB area by 70% vs. TSSOP20; less suitable for space-constrained portable equipment | Select only when legacy SOIC assembly infrastructure exists or thermal dissipation >500 mW is required |
Compared with SN74LVC374APWR and 74LVC374ADB,118, the 74ALVC374PW,118 uniquely combines ultra-low static current (0.2 μA), IOFF-enabled safe power sequencing, and TSSOP20's compact 4.4 mm width - making it optimal for thermally dense, multi-rail embedded systems requiring guaranteed backflow prevention.

FAQ
Does 74ALVC374PW,118 support true bidirectional data flow?
No - it is unidirectional: D inputs feed Q outputs only. While OE enables/disables outputs, there is no internal path from Q to D. For bidirectional bus transceivers, consider dedicated devices like 74LVC245 or 74ALVC164245.
What is the maximum capacitive load the outputs can drive reliably?
Each output is characterized up to 50 pF load capacitance (per Table 9 test conditions). At 3.3 V supply and 24 mA sink/source, VOL ≤ 0.45 V and VOH ≥ 2.2 V are guaranteed - supporting standard 50 Ω transmission lines and typical LVTTL/LVCMOS loads.
Can OE be toggled asynchronously while CP is active?
Yes - OE operates independently of CP and does not affect internal flip-flop states. Outputs respond to OE transitions within ten ≤ 4.6 ns (VCC = 3.0–3.6 V), enabling real-time bus arbitration without disrupting latched data.
Is the exposed pad on the TSSOP20 package electrically connected?
No - the thermal pad (terminal 1 index area) has no electrical function. Per SOT360-1 specification, it may be left floating or connected to GND for thermal improvement, but soldering is optional and carries no electrical requirement.
