74HCT244BQ Description

Short technical summary and product information.

The 74HCT244BQ is a high-speed Si-gate CMOS octal non-inverting buffer/line driver featuring 3-state outputs. These outputs are controlled by output enable inputs, allowing them to assume a high-impedance OFF-state when enabled. This device is pin-compatible with Low-power Schottky TTL (LSTTL).

 

Key electrical characteristics include a supply voltage range of 4.5V to 5.5V, with typical input capacitance of 3.5 pF and power dissipation capacitance of 35 pF per buffer. Propagation delays are specified at 9 ns for the 74HC variant and 11 ns for the 74HCT variant under typical conditions (VCC=5V, CL=15pF). The device offers ESD protection exceeding 2000V (HBM) and 200V (MM).

 

Specified for operation from -40°C to +125°C, the 74HCT244BQ is available in multiple package options, including DHVQFN-20-EP. Its octal bus interface and non-inverting 3-state outputs make it suitable for various digital logic applications requiring bus interfacing and signal buffering.
