ONSEMI (MM74HCT244WM) Buffer / Line Driver, 74HCT244, 4.5 V to 5.5 V, SOIC-20

The MM74HCT244WM is a general purpose high speed inverting octal 3-state Buffer utilizes advanced silicon-gate CMOS technology. It possesses high drive current outputs which enable high speed operation even when driving large bus capacitances. This circuit achieves speeds comparable to low power Schottky devices, while retaining the low power consumption of CMOS. The device is TTL input compatible and has a fan-out of 15 LS-TTL equivalent inputs. MM74HCT device is intended to interface between TTL and NMOS components and standard CMOS devices. This part is also plug-in replacements for LS-TTL devices and can be used to reduce power consumption in existing designs. The device has two active low enables (1G and 2G) and each enable independently controls 4 buffers. All inputs are protected from damage due to static discharge by diodes to VCC and ground.
