Description
The HD74BC540A provides high drivability and operation equal to or better than high speed bipolar standard logic IC
by using Bi-CMOS process. The device features low power dissipation that is about 1/5 of high speed bipolar logic IC,
when the frequency is 10 MHz. The device has eight inverter drivers with three state outputs in a 20 pin package.
When G1 and G2 is low level, this drivers set up output is enable.
Features
• Input/Output are at high impedance state when power supply is off.
• Built in input pull up circuit can make input pins be open, when not used.
• Input is TTL level.
• Wide operating temperature range
Ta = –40 to +85°C
• Ordering Information
