TC4467/TC4468/TC4469

General Description

The TC4467/TC4468/TC4469 devices are a family of

four-output CMOS buffers/MOSFET drivers with 1.2 A

peak drive capability. Unlike other MOSFET drivers,

these devices have two inputs for each output. The

inputs are configured as logic gates: NAND (TC4467),

AND (TC4468) and AND/INV (TC4469).

The TC4467/TC4468/TC4469 drivers can continuously

source up to 250 mA into ground referenced loads.

These devices are ideal for direct driving low current

motors or driving MOSFETs in a H-bridge configuration

for higher current motor drive (see Section 5.0 for

details). Having the logic gates onboard the driver can

help to reduce component count in many designs.

The TC4467/TC4468/TC4469 devices are very robust

and highly latch-up resistant. They can tolerate up to

5 V of noise spiking on the ground line and can handle

up to 0.5 A of reverse current on the driver outputs.

The TC4467/4468/4469 devices are available in

commercial, industrial and military temperature ranges.
