74HC240 Octal Buffer Line Driver IC (74240 IC) DIP-20 Package

The 74HC240 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. These circuits achieve speeds comparable to low-power Schottky devices while retaining the advantage of CMOS circuitry, i.e., high noise immunity and low power consumption. It has a fanout of 15 LS-TTL equivalent inputs. The 74HC240 is an inverting buffer and has two active LOW enables (1G and 2G). Each enable independently controls 4 buffers. All inputs are protected from damage due to static discharge by diodes to VCC and ground.

Features:-

• Typical propagation delay: 12 ns

• 3-STATE outputs for connection to system buses

• Wide power supply range: 2–6V

• Low quiescent supply current: 80 µA (74 Series)

• Output current: 6 mA
