Product details
Overview
HEF4014BT,653 from Nexperia is an 8-bit CMOS static shift register with synchronous parallel enable, designed for parallel-to-serial data conversion in industrial control and legacy digital logic systems. It operates across 3.0 V to 15.0 V supply, features edge-triggered clock (LOW-to-HIGH), supports -40 °C to +85 °C ambient range, and includes input clamp diodes enabling overvoltage-tolerant interfacing.
For engineers reviewing the HEF4014BT,653 datasheet, HEF4014BT,653 pinout, HEF4014BT,653 application, or HEF4014BT,653 equivalent, this device serves as a drop-in replacement for legacy 4000-series shift registers in fixed-function logic designs requiring deterministic timing, low static power, and robust noise immunity without external clock conditioning.
Technical Context
The HEF4014BT,653 implements an 8-bit serial shift register with parallel load capability via a synchronous PE (Parallel Enable) control signal. Its internal structure consists of eight D-type flip-flops cascaded for serial shifting and individually connected to parallel inputs D0–D7.
It uses true CMOS circuitry with symmetrical output drive (VOH ≥ 4.95 V @ VDD = 5 V, VOL ≤ 0.05 V), supports asynchronous reset-free operation, and tolerates slow clock edges - enabling direct interface with microcontroller GPIOs or RC-generated clocks without Schmitt-trigger buffering.
Key Specifications

Applications
| Industrial PLC I/O Expansion | Legacy Microcontroller Peripheral Interface |
|---|---|
Use Scenario: Expanding discrete input/output points on a programmable logic controller using minimal GPIO pins. IC Role / Device Role / Timing Role: Parallel-to-serial converter that aggregates 8 physical sensor/actuator lines into a single serial stream synchronized to the PLC's scan clock. Use Value: Reduces PCB routing complexity and frees MCU pins while maintaining deterministic sampling timing via synchronous CP and PE control. |
Use Scenario: Adding LED or switch matrix control to an 8-bit microcontroller with limited I/O resources. IC Role / Device Role / Timing Role: General-purpose register providing buffered parallel latch and serial shift capability for multiplexed display drivers or keypad scanners. Use Value: Enables software-controlled scan patterns without hardware timers, leveraging the device's static operation and wide VDD range for direct 5 V MCU interface. |
| Test Equipment Data Serialization | Automated Test Fixture Control |
Use Scenario: Capturing parallel status bits from DUT (Device Under Test) and streaming them over UART or SPI interface. IC Role / Device Role / Timing Role: Serial data queueing element that buffers parallel test results and shifts them out synchronously under host command. Use Value: Provides glitch-free data capture with precise setup/hold timing (tsu ≥ 15 ns @ 15 V), eliminating metastability risk in high-speed test sequencing. |
Use Scenario: Controlling solenoid banks or relay modules in production-line test fixtures where timing predictability is critical. IC Role / Device Role / Timing Role: General purpose register used to hold actuation commands until a global strobe triggers simultaneous output update. Use Value: Ensures zero-skew activation of multiple outputs via parallel load (PE), avoiding ripple delays inherent in pure serial chains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit parallel-load shift register applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4014BE | Same pinout and function but rated only to +75 °C; lacks JESD13-B compliance and modern ESD specs | Not suitable for extended industrial temperature range or high-noise factory-floor deployments | Select when cost sensitivity outweighs temperature or reliability requirements |
| 74HC165PW,118 | 3.3 V/5 V only; faster (tPD ≈ 15 ns @ 5 V); requires separate clock and shift/load control signals | Requires additional logic or MCU GPIOs to manage separate SH/LD control - less pin-efficient than PE-based load | Select for high-speed 5 V-only systems needing sub-20 ns propagation and lower power at 5 V |
Compared with CD4014BE and 74HC165PW,118, the HEF4014BT,653 uniquely balances wide-voltage operation, industrial temperature rating, and single-control parallel loading - making it optimal for retrofitting legacy 4000-series designs without redesigning power or timing architecture.

FAQ
What is the maximum clock frequency supported by HEF4014BT,653?
The HEF4014BT,653 supports up to 40 MHz at VDD = 15 V, 30 MHz at VDD = 10 V, and 13 MHz at VDD = 5 V, as specified in Table 7 for fclk(max). These values assume CL ≤ 50 pF and Tamb = 25 °C; derating applies at higher temperatures or capacitive loads.
Can HEF4014BT,653 interface directly with 3.3 V microcontrollers?
Yes - with VDD = 3.3 V, VIH = 2.31 V (min) and VIL = 1.1 V (max) ensure reliable recognition of 3.3 V logic levels. However, output VOH will be ~3.25 V, which may require level-shifting to drive 5 V TTL loads; CMOS loads are fully compatible.
How does the parallel enable (PE) function interact with serial shifting?
When PE = HIGH, the next CP rising edge loads D0–D7 into the register simultaneously. When PE = LOW, each CP rising edge shifts data left (DS → D0 → Q0 → … → Q7), with Q7 as serial output. PE and DS operate independently - no conflict between modes.
Is HEF4014BT,653 suitable for automotive applications?
No - HEF4014BT,653 is not automotive-qualified. It is specified for industrial temperature range (-40 °C to +85 °C) and lacks AEC-Q100 qualification, automotive-specific stress testing, or guaranteed PPAP documentation required for vehicle systems.
