TC4467/TC4468/TC4469
Logic-Input CMOS Quad Drivers
Features General Description High Peak Output Current: 1.2 A Wide Operating Range:
-4.5 V to 18 V Symmetrical Rise/Fall Times: 25 nsec Short, Equal Delay Times: 75 nsec Latch-proof. Will Withstand 500 mA Inductive
Kickback 3 Input Logic Choices:
-AND / NAND / AND + Inv ESD Protection on All Pins: 2 kV 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). Applications General Purpose CMOS Logic Buffer
Driving All Four MOSFETs in an H-Bridge
Direct Small Motor Driver
Relay or Peripheral Drivers
CCD Driver
Pin-Switching Network Driver 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 …
