Logic device/transceiver/encoder

The MM74HC240 3-state buffers utilize advanced silicon-gate CMOS technology. It has a high drive current output, enabling high speed operation even when driving large bus capacitances. These circuits are comparable in speed to low-power Schottky devices, while maintaining the advantages of CMOS circuits, such as high noise immunity and low power consumption. The device has a fanout of 15 LS-TTL equivalent inputs. The MM74HC240 is an inverting buffer with two active low enable pins (1G# and 2G#). Each enable pin can independently control 4 buffers. All inputs are connected to V

The LVT2244 and LVTH2244 are octal buffers and line drivers designed for use as memory address drivers, clock drivers, and bus-based transmitters or receivers that increase printed circuit board density. An equivalent 25ohm series resistor is used to reduce output overshoot and undershoot. The LVTH2244 data input features a bus-hold feature that eliminates the need for external pull-up resistors to hold unused inputs. These buffers and line drivers are designed for low voltage (3.3V) V
