Product details

Overview

HCF4010BEY from STMicroelectronics is a non-inverting hex buffer/converter in 16-pin DIP package, designed for CMOS-to-TTL level translation, current-sinking/source driving, and 1-to-6 multiplexing. It delivers 50 ns typical propagation delay at VDD = 10 V with CL = 50 pF, supports 3–20 V supply operation, and provides ±100 nA input leakage (max) at 18 V.

For engineers reviewing the HCF4010BEY datasheet, HCF4010BEY pinout, HCF4010BEY application, or HCF4010BEY equivalent, key selection considerations include its non-inverting logic function, high sink/source drive capability (up to 36 mA sink at 15 V), wide operating temperature range (−55 °C to +125 °C), and JEDEC JESD13B compliance for B-series CMOS devices.

Technical Context

The HCF4010BEY implements six independent non-inverting buffer stages in a single monolithic CMOS IC, enabling simultaneous level conversion across all channels without signal inversion. Each channel features symmetrical input structure per Figure 2 and supports bidirectional current drive - sourcing up to 1.6 mA and sinking up to 36 mA depending on VDD and load conditions.

Its DC specifications are fully characterized across −55 °C to +125 °C, with guaranteed noise margins of 2.5 V (min) at VDD = 15 V and quiescent current tested to 600 µA max at 20 V. The device operates with VSS referenced to ground and uses dual supply pins (VCC and VDD) as defined in Table 5, where VCC = VDD per application configuration.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Non-inverting hex buffer - preserves input logic state across all six channels
Propagation Delay	50 ns typical at VDD = 10 V, CL = 50 pF - enables reliable timing in ≤10 MHz digital control paths
Supply Voltage Range	3 V to 20 V - supports interoperability across 5 V, 10 V, and 15 V logic domains
Output Sink Current	36 mA max at VDD = 15 V - drives TTL inputs or small LEDs directly without external transistors
Input Leakage	±100 nA max at VDD = 18 V, TA = 25 °C - ensures low power consumption in battery-backed systems
Operating Temperature	−55 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments
Noise Margin	2.5 V min at VDD = 15 V - provides robust immunity against supply ripple and crosstalk

Pinout & Package

Package: Plastic DIP-16 (0.300 inch width), JEDEC MS-001 compliant, with 2.54 mm lead pitch and 3.3 mm body height.

Pin/Terminal	Circuit Role	Design Meaning
1	VCC	Positive supply pin - tied to VDD in standard operation; required for internal biasing
3,5,7,9,11,14	A–F	Independent data inputs - each connects to one buffer stage input
2,4,6,10,12,15	G–L	Corresponding non-inverted outputs - each mirrors its paired input with drive capability
8	VSS	Ground reference - all voltages referenced to this pin; must be connected to system GND
13	NC	No connect - internally unconnected; must remain floating or grounded per layout best practice
16	VDD	Main positive supply - primary power rail; VCC and VDD are electrically equivalent per datasheet

Key Features

Feature	Design Value
CMOS-to-TTL level translation	Validated at 5 V, 10 V, and 15 V supply - eliminates need for discrete level-shifting resistors
High sink/source drive strength	Sinks 36 mA at 15 V - directly interfaces with legacy TTL loads without buffering
100% quiescent current tested	Guaranteed ≤600 µA at 20 V - ensures predictable standby power in always-on subsystems
JEDEC JESD13B compliance	Fully conforms to B-series CMOS specification - assures interoperability with industry-standard logic families
Multiplexer capability (1-to-6)	Single input can drive all six outputs simultaneously - simplifies bus fan-out architecture

Equivalent & Alternatives

The following parts are listed as comparable options for similar non-inverting buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4010BE	Pin-compatible but lower drive (10 mA sink @ 15 V); no 100% I_Q test guarantee	Limited to low-power 5 V systems; not rated for −55 °C operation	Select when cost sensitivity outweighs industrial temp or drive requirements
74HC244N	3-state outputs; higher speed (20 ns t_PD); requires separate OE control per group	Enables bus sharing; unsuitable for simple level translation without OE management	Choose when tri-state capability and 25 MHz operation are mandatory

Compared with CD4010BE and 74HC244N, the HCF4010BEY offers superior temperature range, guaranteed quiescent current, and higher sink current - making it optimal for ruggedized, high-reliability level translation where simplicity and robustness are prioritized over tri-state or ultra-high speed.

FAQ

What is the difference between VCC and VDD pins on the HCF4010BEY?

VCC and VDD are electrically identical supply pins per the datasheet revision history and Table 5. Both must be connected to the same positive supply rail; VCC serves internal biasing while VDD powers the output stages. No functional distinction exists - they are paralleled internally and require common connection.

Can HCF4010BEY drive TTL inputs directly at 5 V supply?

Yes - at VDD = 5 V, VOH ≥ 4.95 V and VOL ≤ 0.05 V meet TTL VIH (≥ 2.0 V) and VIL (≤ 0.8 V) thresholds with 2.5 V noise margin. Its 4 mA sink capability exceeds standard TTL fan-out requirements, enabling direct interface without pull-up resistors.

Is Pin 13 (NC) safe to tie to ground?

Yes - Pin 13 is internally unconnected and may be left floating or grounded per PCB layout best practices. STMicroelectronics confirms no electrical interaction; grounding reduces potential for parasitic coupling in high-noise environments without affecting functionality.

Does HCF4010BEY support 3.3 V logic inputs?

No - minimum recommended VDD is 3 V, but VIH at 3 V is only ~1.2 V (interpolated from Table 6), below standard 3.3 V logic "1" threshold (≥ 2.0 V). For 3.3 V systems, use with ≥5 V supply or add external level-shifting; native 3.3 V input compatibility is not supported.
