The TC4428M is a 1.5A dual high-speed MOSFET driver with one inverting and one non-inverting output, housed in an 8-pin CERDIP package measuring 9.78mm maximum length and 7.75mm maximum width. It operates from a 4.5V to 18V supply, drives 1000pF loads in 25ns typical, and has 40ns typical propagation delay. The device features matched rise and fall times, 7Ω output impedance, and latch-up protection withstanding 0.5A reverse current. Input terminals tolerate negative voltages up to 5V and are ESD protected to 4kV. It is qualified for operation from -55°C to +125°C with a maximum junction temperature of +150°C and thermal resistance of 150°C/W. The part is pin-compatible with the TC426M/427M/428M family.
The TC4426/4427/4428 are improved versions of the earlier TC426/427/428 family of buffer/drivers (with which they are pin compatible). They will not latch up under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (of either polarity) occurs on the ground pin. They can accept, without damage or logic upset, up to 500 mA of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against up to 2kV of electrostatic discharge. As MOSFET drivers, the TC4426/4427/4428 can easily switch 1000pF gate capacitances in 25 nsec, and provide low enough impedances in both the ON and OFF states to ensure the MOSFET's intended state will not be affected by large transients. However, the recommended pin-compatible drivers are the TC4426A/27A/28A. These drivers have matched input to output leading edge and falling edge delays, tD1 and tD2, for processing short duration pulses in the 25 nsec range. They are pin compatible with the TC4426/27/28.
