General Description
The TC4426AM/TC4427AM/TC4428AM are improved versions of the earlier TC4426M/TC4427M/TC4428M family of MOSFET drivers. In addition to matched rise and fall times, the TC4426AM/TC4427AM/TC4428AM devices have matched leading and falling edge propagation delay times. These devices are highly latch-up resistant 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 Electrostatic Discharge (ESD) up to 4 kV. The TC4426AM/TC4427AM/TC4428AM MOSFET drivers can easily charge/discharge 1000 pF gate capacitances in under 30 ns, while providing low enough impedances in both the on and off states to ensure the MOSFET's intended state will not be affected, even by large transients.

3.0 PIN DESCRIPTIONS
3.3 Outputs A & B (OUT A and OUT B)
The descriptions of the pins are listed in Table 3-1. MOSFET driver OUT A & B are low-impedance, CMOS, push-pull style outputs. The pull-down and pullup devices are of equal strength, making the rise and fall times equivalent.

8-Pin Symbol CERDIP 1 2 3 4 5 6 7 8 NC IN A GND IN B OUT B VDD OUT A NC Input A Ground Input B Output B
3.4
No connection
Supply Input (VDD)
Supply input Output A No connection
The VDD input is the bias supply for the MOSFET driver and is rated for 4.5V to 18V, with respect to the ground pin. The VDD input should be bypassed with local ceramic capacitors. The value of these capacitors should be chosen based on the capacitive load that is being driven.
3.1
Inputs A & B (IN A and IN B)
MOSFET driver IN A & B are high-impedance, TTL/CMOS-compatible inputs. These inputs also have 300 mV of hysteresis between the high and low thresholds, which prevents output glitching even when the rise and fall time of the input signal is very slow.
3.2
Ground (GND)
The GND pin is the return path for both the bias current and the high peak current that discharges the external load capacitance. The ground pin should be tied into a ground plane or have a very short trace to the bias supply source return.
