Product details

Overview

HEF4094BT,653 from Nexperia is an 8-bit CMOS serial-in/parallel-out shift-and-store register with independent shift and storage clocks, 3-state outputs, dual serial outputs (QS1/QS2) for cascading, and operation across 3.0 V to 15.0 V supply. It features strobe-controlled parallel output latching, high-impedance output enable (OE), and operates from −40 °C to +125 °C - used in LED matrix drivers, remote control holding registers, and serial-to-parallel data conversion in industrial control panels.

For engineers reviewing the HEF4094BT,653 datasheet, HEF4094BT,653 pinout, HEF4094BT,653 application, or HEF4094BT,653 equivalent, key selection considerations include its dual-edge-cascadable serial outputs (QS1 on CP↑, QS2 on CP↓), independent STR clocking for output latching, 3-state OE control, wide VDD range (3–15 V), and SO16 package compatibility with legacy 4000-series logic designs.

Technical Context

The HEF4094BT implements a two-stage pipeline: an 8-bit shift register accepting serial data on CP rising edges, and a separate 8-bit storage register loaded synchronously on STR HIGH. Outputs QP0–QP7 reflect storage register contents only when OE is HIGH; OE LOW forces all outputs into high-impedance state without affecting internal register states.

Its dual serial outputs support daisy-chaining: QS1 delivers shifted data on the same CP↑ edge (enabling fast-edge cascading), while QS2 delivers the same data on the subsequent CP↓ edge (supporting slower-edge timing margins). Input clamp diodes allow interfacing to voltages exceeding VDD when used with current-limiting resistors.

Key Specifications

Parameter	Value and Actual Design Meaning
Function	8-bit serial-in/parallel-out shift-and-store register with 3-state outputs
Supply Voltage Range	3.0 V to 15.0 V - supports mixed-voltage system integration and legacy 5/10/15 V logic rails
Operating Temperature	−40 °C to +125 °C - qualified for extended industrial environments
Propagation Delay (CP to QPn)	Min 47 ns at VDD = 15 V - enables reliable operation up to 28 MHz maximum clock frequency
Output Drive Strength	IOL = 2.4 mA / IOH = −2.4 mA at VDD = 15 V - sufficient to directly drive LEDs or TTL inputs
Input Clamp Diodes	Integrated - permits safe interface to signals exceeding VDD using external current-limiting resistors
ESD Protection	HBM > 2000 V, CDM > 1000 V - enhances robustness in handling and assembly

Pinout & Package

HEF4094BT,653 is supplied in SO16 (SOT109-1) plastic small outline package: 16-pin, 3.9 mm body width, 1.27 mm lead pitch, surface-mount compatible.

Pin/Terminal	Circuit Role	Design Meaning
1 (STR)	Strobe input	Loads shift register contents into storage register on HIGH; asynchronous to CP
2 (D)	Serial data input	Accepts new bit on each LOW-to-HIGH CP transition
3 (CP)	Shift clock input	Drives serial shifting on rising edge; controls QS1 (on CP↑) and QS2 (on next CP↓)
4–7, 11–14 (QP0–QP7)	Parallel outputs	Reflect storage register contents when OE = HIGH; high-impedance when OE = LOW
8 (VSS)	Ground	Reference for all inputs, outputs, and internal logic
9 (QS1)	Serial output (fast)	Same data as QP7 one CP↑ earlier - optimized for high-speed cascading
10 (QS2)	Serial output (slow)	Same data as QP7 one full CP cycle later - accommodates slower clock edges
15 (OE)	Output enable	Active-HIGH; disables all QPn outputs to high-Z without altering register states
16 (VDD)	Supply voltage	Supports 3.0–15.0 V; powers internal logic and output drivers

Key Features

Feature	Design Value
Dual serial outputs (QS1/QS2)	Enables flexible daisy-chaining: QS1 for fast-clock systems, QS2 for slow-clock margin tolerance
Independent shift/storage clocks	CP controls shifting; STR controls latching - decouples data loading from output update timing
3-state parallel outputs with OE	Allows bus sharing and dynamic output isolation without external logic or pull-ups
Wide VDD range (3–15 V)	Eliminates level-shifting in mixed-supply systems and supports legacy 4000-series voltage scaling
Input clamp diodes	Permits direct connection of overvoltage control signals (e.g., 24 V panel inputs) via series resistors

Applications

LED Matrix Driver

Remote Control Holding Register

Use Scenario: Driving 8×N LED arrays in industrial status panels where microcontroller GPIOs are limited.

IC Role / Device Role / Timing Role: Serial-to-parallel converter that buffers and latches column data under microcontroller command, then drives LEDs via constant-current sinks.

Use Value: Reduces MCU pin count by 8:1; enables synchronized column refresh using STR and OE for flicker-free display updates.

Use Scenario: Capturing and holding button-press codes from infrared remote receivers in HVAC or AV equipment.

IC Role / Device Role / Timing Role: Shift register capturing serial IR pulse train, then latched into storage register upon frame completion for stable parallel readout.

Use Value: Eliminates need for continuous polling; allows host MCU to read stable parallel data only when required, reducing interrupt load.

Industrial I/O Expander

Legacy System Bus Interface

Use Scenario: Adding 8-bit parallel digital output capability to PLC modules using existing serial control lines.

IC Role / Device Role / Timing Role: Serial-input latch providing isolated, 3-state parallel outputs compatible with 24 V industrial logic levels via external pull-ups.

Use Value: Enables retrofitting of modern microcontrollers into older systems without redesigning backplane wiring or adding level translators.

Use Scenario: Interfacing 8-bit microprocessors (e.g., Z80, 8085) with peripheral devices requiring synchronous parallel data transfer.

IC Role / Device Role / Timing Role: Synchronous shift-and-latch buffer that accepts processor-generated serial data and presents it as stable parallel byte on STR assertion.

Use Value: Provides clean timing separation between data shift and output update - critical for meeting setup/hold requirements of vintage peripherals.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 8-bit shift-and-store register applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4094BE	Same function but TI-manufactured; wider propagation delay (min 200 ns at 5 V), lower max f_max (6 MHz at 5 V)	Limited to low-speed 5 V systems; lacks QS2 output for slow-edge cascading	Select when cost-sensitive 5 V-only designs require second-source availability and timing margins exceed 200 ns
74HC595	Single serial output (Q7S), no QS2; OE active-LOW; higher speed (f_max = 100 MHz at 4.5 V) but narrower VDD range (2–6 V)	Not suitable for 10/15 V operation or dual-edge cascade topologies; requires inverted OE control logic	Select for high-speed 3.3/5 V digital systems where single-output chaining suffices and power supply is constrained

Compared with CD4094BE and 74HC595, the HEF4094BT,653 uniquely supports 3–15 V operation, provides dual-cascade outputs for timing-flexible daisy-chaining, and maintains full functionality across industrial temperature extremes - making it the only choice for mixed-voltage, high-reliability, or legacy-compatible serial-to-parallel expansion.

FAQ

What is the purpose of the dual serial outputs QS1 and QS2?

QS1 outputs shifted data on the same CP rising edge, enabling tight-timing cascading in high-speed systems. QS2 outputs the identical data on the subsequent CP falling edge, accommodating slower clock edges and easing timing closure in long daisy chains - both outputs support seamless multi-device expansion without added logic.

Can HEF4094BT,653 operate reliably at 15 V and +125 °C?

Yes - the device is fully specified from −40 °C to +125 °C and supports VDD up to 15.0 V per JEDEC JESD13-B. Static and dynamic parameters (VOH/VOL, t_P, f_max) are guaranteed across this full range, and thermal derating is defined for SO16 package power dissipation above 110 °C.

How does the strobe (STR) input interact with the shift clock (CP)?

STR is asynchronous to CP: when STR goes HIGH, the current contents of the 8-bit shift register are immediately copied into the storage register. This decouples data shifting (governed by CP) from output updating (governed by STR), allowing independent control of data capture and presentation timing - critical for glitch-free parallel output updates.

Is there any risk of bus contention when multiple HEF4094BT,653 devices share parallel outputs?

No - the 3-state outputs are controlled by OE. When OE is LOW, all QP0–QP7 outputs enter high-impedance state regardless of STR or CP activity. This allows multiple devices to share a common bus; only the device with OE HIGH actively drives the lines, eliminating contention without external bus transceivers.
