Product details
Overview
74LV377PW,118 from NXP Semiconductors (formerly Philips) is an octal positive-edge-triggered D-type flip-flop with active-low data enable, designed for low-voltage addressable register and data synchronization applications. It operates from 1.0 V to 3.6 V, delivers 77 MHz maximum clock frequency at VCC = 3.3 V, features 13 ns typical propagation delay (CP to Qn), and supports industrial temperature range (–40°C to +125°C) in TSSOP20 package.
For engineers reviewing the 74LV377PW,118 datasheet, 74LV377PW,118 pinout, 74LV377PW,118 application, or 74LV377PW,118 equivalent, key selection criteria include low-voltage compatibility (1.0–3.6 V), edge-triggered synchronous load capability, TTL-level input acceptance at 2.7–3.6 V, ground bounce (VOLP) and undershoot (VOHV) performance, and pin/function compatibility with 74HC/HCT377 families.
Technical Context
The 74LV377PW,118 implements eight independent D-type latches sharing a common clock (CP) and a single active-low data enable (E). Its operation requires stable E one setup time before the LOW-to-HIGH CP transition to ensure predictable loading of D0–D7 into Q0–Q7 outputs. All flip-flops are edge-triggered and non-transparent - outputs change only on the rising edge of CP when E is asserted.
It belongs to the LV CMOS logic family optimized for low-power, low-noise operation across wide supply ranges. Input thresholds scale with VCC, enabling interoperability with both LVCMOS and TTL interfaces at higher VCC levels (2.7–3.6 V), while maintaining robust noise margins and controlled output drive (±25 mA per standard output).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.0 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V systems without level shifters |
| fmax | 77 MHz at VCC = 3.3 V - supports high-speed address/data latching in microcontroller peripherals and bus interfaces |
| tPHL/tPLH | 13 ns typical (CL = 15 pF) - ensures tight timing control for synchronous register updates in real-time control paths |
| tsu (Dn to CP) | 13 ns minimum at VCC = 3.0–3.6 V - defines minimum data stability window before clock edge for reliable capture |
| VOL / VOH | 0.25 V / 2.40 V (IO = 6 mA, VCC = 3.0 V) - guarantees rail-compatible logic levels driving standard CMOS/TTL loads |
| ICC (quiescent) | 20 µA typical at VCC = 3.6 V - supports ultra-low static power in battery-backed or always-on register storage |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor embedded applications |
Pinout & Package
74LV377PW,118 is housed in a 20-lead plastic thin shrink small outline package (TSSOP Type I), SOT360-1, with 0.65 mm lead pitch and 4.4 mm body width - suitable for high-density PCB layouts requiring thermal and space efficiency.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E | Active-low data enable - gates simultaneous loading of all eight D inputs; must be stable ≥13 ns before CP rising edge |
| 2,5,6,9,12,15,16,19 | Q0–Q7 | Registered outputs - retain state until next valid CP edge with E low; standard drive strength (±25 mA) |
| 3,4,7,8,13,14,17,18 | D0–D7 | Data inputs - sampled on CP rising edge only when E is low; accept TTL levels at VCC ≥ 2.7 V |
| 10 | GND | Ground reference - dedicated return path for logic and switching currents; decoupling required within 5 mm |
| 11 | CP | Clock input - rising-edge sensitive; VIH/VIL thresholds scale with VCC; max 77 MHz at 3.3 V |
| 20 | VCC | Positive supply - powers all internal logic and output drivers; requires local 100 nF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Low-voltage operation | Functional down to 1.0 V supply - supports energy-efficient designs in portable and IoT edge nodes |
| TTL-input compatibility | Accepts standard TTL logic levels at VCC = 2.7–3.6 V - simplifies integration with legacy 5 V subsystems via level-shifter-free interfacing |
| Controlled output transients | Typical VOLP = 0.8 V and VOHV = 2.0 V at VCC = 3.3 V - reduces ground bounce and supply undershoot in multi-load systems |
| Pin/function compatibility | Direct replacement for 74HC377 and 74HCT377 - enables drop-in upgrade to lower voltage and reduced power without layout changes |
| Industrial temperature grade | Rated –40°C to +125°C - validated for use in motor control, power conversion, and automotive body electronics |
Applications

IC Role / Device Role / Timing Role: Hardwired octal latch providing deterministic timing and lower power than programmable equivalents. Use Value: 20 µA quiescent current and 77 MHz speed offer better power/performance trade-off than generic programmable logic for static register functions. |
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 |
|---|---|---|---|
| 74LV377D,118 | SO20 package (SOT163-1); 7.5 mm body width; higher thermal resistance (θJA = 120 K/W vs. 160 K/W for TSSOP) | Better suited for prototyping or manual assembly; less dense footprint than TSSOP | Select when board space permits larger package or hand-soldering is required |
| SN74LV377APWR | Texas Instruments variant; identical electrical specs but different AC characterization limits (e.g., tPLH max = 22 ns @ CL = 50 pF vs. 36 ns for NXP) | Validated for TI-specific reference designs; minor timing margin differences in high-speed layouts | Prefer for TI ecosystem designs or when sourcing diversity is required |
Compared with 74LV377PW,118, the SO20 variant offers easier rework but sacrifices board density and thermal performance, while the TI SN74LV377APWR provides equivalent functionality with tighter AC tolerances - making it preferable in TI-based systems where layout parasitics demand stricter timing margins.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74LV377PW,118?
The 74LV377PW,118 is guaranteed to function down to VCC = 1.0 V with input levels referenced to GND or VCC. DC electrical characteristics are fully specified from VCC = 1.2 V to 3.6 V, enabling reliable use in ultra-low-power 1.2 V and 1.8 V domains. At 1.0 V, functionality is maintained but DC parameters like VOH/VOL are not guaranteed.
Does the 74LV377PW,118 support TTL-level inputs?
Yes - the 74LV377PW,118 accepts standard TTL input voltage levels when VCC is between 2.7 V and 3.6 V. Its VIH threshold is 2.0 V (min) and VIL is 0.8 V (max) in this range, ensuring compatibility with 5 V TTL outputs without external level shifters, a key advantage over standard LVCMOS-only devices.
What is the purpose of the E (enable) pin on the 74LV377PW,118?
The E pin on the 74LV377PW,118 is an active-low data enable that controls whether D0–D7 inputs are loaded into Q0–Q7 outputs on the next CP rising edge. When E is HIGH, outputs retain their previous state regardless of CP transitions. This enables precise synchronization of data capture windows in address/data multiplexing and burst-mode interfaces.
Can the 74LV377PW,118 replace a 74HC377 in an existing design?
Yes - the 74LV377PW,118 is pin and function compatible with the 74HC377 and 74HCT377. It operates at lower voltages (1.0–3.6 V vs. 2.0–6.0 V), draws significantly less quiescent current (20 µA vs. ~40 µA), and maintains identical logic behavior and timing architecture, allowing direct substitution with no PCB changes required.
What are the thermal limitations of the 74LV377PW,118 in TSSOP package?
The 74LV377PW,118 in TSSOP20 (SOT360-1) has a power dissipation limit of 400 mW at ambient temperatures up to +60°C, derating linearly by 5.5 mW/K above that point. Its θJA is approximately 160 K/W, meaning junction temperature rise is ~64°C at 400 mW - requiring adequate copper area and airflow in high-power-density applications.
