Overview of the SGS-THOMSON CMOS AND Gates Series

The datasheet in question pertains to SGS-THOMSON’s series of CMOS AND gates. These include the HCC4073B, HCC4081B, and HCC4082B, designed to operate in extended temperature ranges, and their intermediate temperature range counterparts, the HCF4073B, HCF4081B, and HCF4082B. These integrated circuits are used for implementing the AND function in digital circuits and enhance the existing family of COS/MOS gates.

Key Features and Advantages

The devices showcased in the datasheet are characterized by medium-speed operation, with typical propagation delays of 85ns (tPLH) and 65ns (tPHL) at 10V. They exhibit a low quiescent current, which is fully specified up to 20V for the HCC variant. This low input current of 100nA at 18V and 25°C for the HCC type assures power efficiency. The gates have been thoroughly tested for their quiescent current, ensuring reliability and compliance with the JEDEC standard no. 134 for “B” series CMOS devices.

Package Options and Part Identification

Customers can choose between numerous package forms, including:

– Plastic Package

– Ceramic Frit Seal Package

– Micro Package

– Plastic Chip Carrier

And identification for ordering is through a code system: HCC4OXXBF, HCF4OXXBMI, HCFAOXXBEY, and HCFAOXXBC1.

Technical Specifications and Ratings

The datasheet delineates the absolute maximum ratings for the devices, cautioning against exceeding these limits to avoid permanent damage. For the HCC types, the supply voltage ranges from -0.5 to 18V, while for the HCF types, it is -0.5 to 15V. Their operating temperature spans from -55°C to +125°C for HCC devices and from -40°C to +85°C for HCF types.

Under recommended operating conditions, the supply voltage for HCC types is 3 to 18V and for HCF types 3 to 15V, with input voltage up to VDD, and a typical operating temperature range as specified for each type.

Electrical Characteristics

Stated electrical characteristics cover static behavior over the recommended operating conditions, including quiescent current as low as 0.01 μA supporting minimal power consumption, and strong output voltage levels with a high voltage (VOH) maintaining close to supply level, and a low voltage (VOL) almost at ground.

Additionally, the noise margin for both high (“1”) and low (“0”) levels is assured at a minimum of 1V, providing good signal integrity and tolerance to voltage fluctuations, especially important in complex digital circuits.
