74HCT244D,653 Description

Short technical summary and product information.

The 74HCT244D,653 from NXP Semiconductors is an octal buffer/line driver featuring 3-state outputs. This device can function as two 4-bit buffers or a single 8-bit buffer, controlled by two output enable signals (1OE and 2OE). A high signal on the output enable pin forces the outputs into a high-impedance OFF-state.

 

This buffer/line driver supports a wide supply voltage range from 2.0 V to 6.0 V and operates across a temperature range of -40°C to +125°C. It offers CMOS low power dissipation and high noise immunity. The inputs include clamp diodes, allowing for the use of current-limiting resistors to interface with voltages exceeding VCC.

 

The 74HCT244D,653 is available in a 20-SOIC package with a body width of 7.5 mm. It is designed for surface mount applications. The device complies with JEDEC standards JESD8C and JESD7A, and features ESD protection exceeding 2000 V (HBM class 2) and 1000 V (CDM class C3).

 

Key electrical characteristics include a logic type of Buffer, Non-Inverting, and 3-state output type. It has 2 elements, each with 4 bits. The operating voltage is specified between 4.5V and 5.5V, with an output current of 6mA.
