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 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 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.

Features

• 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

Applications:

• General Purpose CMOS Logic Buffer

• Driving All Four MOSFETs in an H-Bridge

• Direct Small Motor Driver

• Relay or Peripheral Drivers

The devices are available in commercial, industrial and military temperature ranges.
