STMicroelectronics HCF4030BEY

Overview

HCF4030BEY from STMicroelectronics is a quad exclusive-OR (XOR) gate IC in 14-pin DIP package, operating across 3–20 V supply, with typical propagation delay of 65 ns at 10 V/50 pF, output impedance of 500 Ω, and input leakage ≤100 nA at 18 V - used in parity generation, checking, and 8-bit arithmetic circuits.

For engineers reviewing the HCF4030BEY datasheet, HCF4030BEY pinout, HCF4030BEY application, or HCF4030BEY equivalent, key selection factors include supply voltage range (3–20 V), XOR logic function per gate, DIP-14 mechanical compatibility, temperature rating (−55°C to +125°C), and JEDEC JESD13B compliance for B-series CMOS devices.

Technical Context

The HCF4030BEY implements four independent CMOS XOR gates using complementary n-channel and p-channel enhancement-mode transistors per gate. Each gate accepts two inputs and delivers one true-output XOR result without internal inversion or buffering.

It operates over extended supply (3–20 V) and temperature (−55°C to +125°C) ranges, with noise margins specified at 1 V (5 V), 2 V (10 V), and 2.5 V (15 V). Input protection diodes and low quiescent current (≤4 µA at 5 V, ≤600 µA at 20 V) support robust industrial use.

FAQ

What is the maximum supply voltage rating for HCF4030BEY?

The absolute maximum supply voltage (VDD) is +22 V, but the recommended operating range is 3 V to 20 V. Operation at 20 V is fully characterized per datasheet - including propagation delay, output drive, and quiescent current - making it suitable for high-voltage industrial logic where 15 V rails are common.

Does HCF4030BEY require external pull-up or pull-down resistors on inputs?

No. All inputs feature built-in protection diodes and CMOS threshold design that ensures stable logic levels across the full supply range without external biasing. Input leakage remains ≤100 nA at 18 V, so high-impedance source drivers (e.g., microcontroller GPIO) interface directly without risk of floating states.

Can HCF4030BEY drive standard TTL loads?

Yes - at VDD ≥ 10 V, VOH reaches 9.95 V and IOL supports up to 6.8 mA sink current, exceeding TTL VIH (2 V) and fan-out requirements. However, direct connection to 5 V TTL inputs requires no level shift, while driving 3.3 V logic may need series resistance or clamping to avoid overstress.

Is HCF4030BEY RoHS compliant and lead-free?

Yes. As a STMicroelectronics device manufactured post-2006, HCF4030BEY meets RoHS Directive 2011/65/EU and is lead-free with matte tin finish on leads. The DIP-14 package uses halogen-free molding compound and complies with JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life at ≤30°C/60% RH).
