SN74HCT244N Description

Short technical summary and product information.

The SN74HCT244N is an octal buffer and line driver manufactured by Texas Instruments. It operates within a voltage range of 4.5V to 5.5V and features TTL-compatible CMOS inputs with tri-state outputs. This device is organized as two independent 4-bit buffers, each controlled by a separate output-enable (OE) input. When OE is low, data passes non-inverted from the A inputs to the Y outputs. When OE is high, the outputs enter a high-impedance state.

 

Key electrical characteristics include high-current outputs capable of driving up to 15 LSTTL loads, low power consumption with a maximum ICC of 80µA, and a typical propagation delay of 13ns. The output drive is ±6mA at 5V, and the input current is a maximum of 1µA. These features make the SN74HCT244N suitable for improving performance and density in applications such as 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.

 

The SN74HCT244N is available in a 20-pin PDIP (Plastic Dual In-line Package) with through-hole mounting. The operating temperature range is -40°C to 85°C (TA). This component is designed for applications requiring reliable buffering and signal driving in a through-hole form factor.
