Product details

Overview

74LV165D,118 from Nexperia is an 8-bit parallel-in/serial-out shift register with asynchronous parallel load (PL), clock enable (CE), complementary serial outputs (Q7 and Q7), and wide supply range (1.0 V to 5.5 V). It operates from −40 °C to +125 °C, supports TTL-level interfacing at 2.7–3.6 V, and delivers propagation delay as low as 11 ns at 5 V - used in industrial I/O expansion, LED matrix controllers, and microcontroller GPIO extender circuits.

For engineers reviewing the 74LV165D,118 datasheet, 74LV165D,118 pinout, 74LV165D,118 application, or 74LV165D,118 equivalent, key selection criteria include its dual-output architecture (Q7/Q7), CE-controlled synchronous shifting, PL-triggered parallel capture, and SO16 package compatibility with legacy 74-series PCB footprints.

Technical Context

The device implements an 8-stage static CMOS shift register with edge-triggered clock (CP) on LOW-to-HIGH transitions and active-low parallel load (PL) that asynchronously loads D0–D7. Clock enable (CE) gates CP input when HIGH, enabling precise timing control in daisy-chained configurations.

Its dual serial outputs provide both true (Q7) and inverted (Q7) data for direct connection to differential receivers or logic-level inversion without external gates. Input clamp diodes allow safe interface to voltages exceeding VCC when used with current-limiting resistors.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage range	1.0 V to 5.5 V - enables single-rail operation across 1.2 V logic, 3.3 V embedded, and 5 V legacy systems
Operating temperature	−40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives
Propagation delay (t_pd)	11 ns (min) at V_CC = 5 V - supports >30 MHz clock rates in high-speed serial data pipelines
Input voltage thresholds	V_IL ≤ 0.3×V_CC, V_IH ≥ 0.7×V_CC - ensures robust noise margin and TTL compatibility at 3.3 V
Output drive strength	±25 mA per output - directly drives LEDs, small-signal MOSFET gates, or 50 Ω transmission lines
Power dissipation capacitance	C_PD = 35 pF at 3.3 V - enables accurate dynamic power estimation in battery-powered designs

Pinout & Package

74LV165D,118 is housed in a plastic small outline package (SO16, SOT109-1) with 16 leads and 3.9 mm body width, compatible with standard wave-solder and reflow profiles.

Pin/Terminal	Circuit Role	Design Meaning
1 (PL)	Parallel load enable	Active-LOW asynchronous latch control - loads D0–D7 into register regardless of clock state
2 (CP)	Shift clock input	Edge-triggered (LOW-to-HIGH) - advances data through all 8 stages on each valid transition
7 (Q7)	True serial output	MSB serial output after full 8-bit shift - connects directly to next stage's DS or MCU UART RX
9 (Q7)	Inverted serial output	Complementary to Q7 - eliminates need for external inverter in differential signaling paths
10 (DS)	Serial data input	Accepts serial bitstream during shift mode (PL = HIGH) - synchronized to CP edge
11–14, 3–6 (D0–D7)	Parallel data inputs	8-bit wide parallel bus interface - mapped to physical pins in non-sequential order per SO16 layout
15 (CE)	Clock enable	Active-LOW gate for CP - freezes register state when HIGH, enabling precise multi-device synchronization
16 (V_CC) / 8 (GND)	Power supply terminals	Single-supply operation with decoupling recommended within 10 mm of pins 8 and 16

Key Features

Feature	Design Value
Wide V_CC range (1.0–5.5 V)	Eliminates level-shifting in mixed-voltage systems - e.g., interfaces 1.2 V FPGA I/O to 5 V display drivers
Asynchronous parallel load (PL)	Enables immediate capture of sensor or bus data without waiting for clock edges - critical for real-time sampling
Complementary Q7/Q7 outputs	Reduces BOM count by removing external inverters in clock/data recovery or RS-422-like interfaces
Clamp diode-equipped inputs	Permits safe connection to 12 V control signals using simple series resistors - no external protection required
JESD78 Class II Level B latch-up immunity	Withstands >100 mA transient currents - ensures reliability in noisy industrial environments with ESD or inductive kickback

Equivalent & Alternatives

The following parts are listed as comparable options for similar parallel-in/serial-out shift register applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LV165AIPWRE4	TI variant in TSSOP-16; identical logic but different thermal resistance (8.5 mW/K derating above 91 °C vs. 12.4 mW/K for SO16)	Same functional behavior but lower power density - preferred for space-constrained PCBs with forced-air cooling	Select when board area is constrained and thermal management includes airflow; verify SO16 footprint compatibility is not required
74HC165PW,118	Nexperia HC version: higher V_CC min (2.0 V), slower t_pd (26 ns @ 4.5 V), no 1.2 V operation	Lacks ultra-low-voltage support - unsuitable for battery-powered 1.8 V systems but offers higher noise immunity at 5 V	Choose only if design operates strictly at 4.5–5.5 V and requires stronger output drive (±5.2 mA vs. ±25 mA) is not needed

Compared with SN74LV165AIPWRE4, the 74LV165D,118 provides superior thermal stability in sealed enclosures due to SO16's higher power dissipation limit; versus 74HC165PW,118, it enables direct integration into 1.2–2.0 V SoC domains without level shifters - reducing component count and signal integrity risk.

FAQ

What is the minimum supply voltage for reliable operation of the 74LV165D,118?

The 74LV165D,118 is fully specified down to 1.0 V, with guaranteed functionality including propagation delay, setup/hold times, and output drive strength across the full −40 °C to +125 °C range. At 1.2 V, t_pd is 115 ns max; static parameters like V_IH and V_IL scale linearly with V_CC, ensuring predictable logic thresholds.

Can the 74LV165D,118 be used in daisy-chained configurations without external logic?

Yes - the Q7 output connects directly to the DS input of the next device, and CE can be tied together across all stages to enable simultaneous shifting. The complementary Q7 output allows termination matching and reduces reflections in long-chain layouts, supporting reliable operation up to 30 MHz with proper PCB routing.

Does the 74LV165D,118 require external pull-up or pull-down resistors on control inputs?

No - all control inputs (PL, CP, CE, DS) have internal clamp diodes and defined logic thresholds. However, for noise immunity in high-EMI environments, a 10 kΩ pull-down on PL and CE is recommended to prevent spurious loading or clocking during power-up or reset sequences.

How does the latch-up immunity specification impact system-level reliability?

The JESD78 Class II Level B rating (>100 mA) means the device withstands transient overcurrent events - such as relay coil flyback, relay contact arcing, or ESD discharge - without permanent failure. This eliminates need for external current-limiting components in industrial control inputs, reducing BOM cost and board area.
