STMicroelectronics M74HCT08B1R Quad 2-Input AND Gate

The M74HCT08B1R is a high-performance integrated circuit from the renowned semiconductor manufacturer STMicroelectronics. This device is a member of the HCT (High-speed CMOS TTL-compatible) family and functions as a quad 2-input AND gate. It is designed to operate with a power supply range of 4.5V to 5.5V, which makes it compatible with TTL logic levels while offering the low power consumption of CMOS technology.

Each of the four independent AND gates in the M74HCT08B1R is capable of driving 10 LSTTL loads, which is indicative of its high fan-out capability. The inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of Vcc. This feature is particularly useful for protecting the device against high-energy transients that may occur in industrial environments.

The M74HCT08B1R comes in a DIP-14 (Dual In-line Package) form factor, which is a common package for through-hole mounting. This makes it easy to insert into standard prototyping boards and is suitable for applications that require robust physical connections.

Key Features:

• Advanced high-speed CMOS technology
• TTL input compatibility: VIL = 0.8V (max), VIH = 2V (min)
• Low quiescent current: 20µA (max) at 25°C
• High noise immunity characteristic of CMOS devices
• Output drive capability: 10 LSTTL loads
• Power down protection on inputs
• Static operation: no clocks or refreshing required
• Symmetrical output impedance: |Ioh| = Iol = 4 mA (min)
• Pin and function compatible with 74 series logic
• ESD performance: HBM > 1KV; MM > 200V

The M74HCT08B1R is ideal for applications that require logical data processing, signal gating, and input/output buffering. Its high-speed performance and compatibility with older TTL logic make it a versatile choice for a wide range of digital applications, including computers, data processing, control systems, and communication equipment.

STMicroelectronics' commitment to quality and reliability ensures that the M74HCT08B1R is a reliable component for both commercial and industrial electronic systems. Its robustness and performance characteristics are well-suited for the demanding requirements of modern electronic designs.
