Microchip Technology, Inc. 1.5A Dual Non-Inverting High-Speed MOSFET Driver TC427

Description
The TC426/TC427/TC428 are dual CMOS high-speed drivers. A TTL/CMOS input voltage level is translated into a rail-to-rail output voltage level swing. The CMOS output is within 25mV of ground or positive supply. The low impedance, high-current driver outputs swing a 1000pF load 18V in 30nsec. The unique current and voltage drive qualities make the TC426/TC427/TC428 ideal power MOSFET drivers, line drivers, and DC-to-DC converter building blocks. Input logic signals may equal the power supply voltage. Input current is a low 1A, making direct interface to CMOS/bipolar switch-mode power supply control ICs possible, as well as open-collector analog comparators. Quiescent power supply current is 8mA maximum. The TC426 requires 1/5 the current of the pin-compatible bipolar DS0026 device. This is important in DC-to-DC converter applications with power efficiency constraints and high-frequency switch-mode power supply applications. Quiescent current is typically 6mA when driving a 1000pF load 18V at 100kHz. The inverting TC426 driver is pin-compatible with the bipolar DS0026 and MMH0026 devices. The TC427 is noninverting; the TC428 contains an inverting and non-inverting driver. Other pin compatible driver families are the TC1426/27/28, TC4426/27/28, and TC4426A/27A/28A. For product comparison, please consider: TC4427A Additional Features High-Speed Switching (CL = 1000pF): 30nsec High Peak Output Current: 1.5A High Output Voltage Swing: VDD – 25mV GND +25mV Low Input Current (Logic '0' or '1'): 1mA TTL/CMOS Input Compatible Available in Inverting and Noninverting Configurations Wide Operating Supply Voltage: 4.5V to 18V Current Consumption: Inputs Low: 0.4mA Inputs High: 8mA Single Supply Operation Low Output Impedance: 6Ω Pinout Equivalent of DS0026 and MMH0026 Latch-Up Resistant: Withstands > 500mA Reverse Current

The TC427 is a dual noninverting high-speed CMOS MOSFET driver designed to translate TTL/CMOS input levels into rail-to-rail output swings within 25 mV of the supply rails. It delivers a peak output current of 1.5 A and switches a 1000 pF load 18 V in 30 ns under standard conditions. Operating from a 4.5 V to 18 V single supply, it draws 0.4 mA with logic low inputs and 8 mA maximum with logic high inputs. The device features low output impedance of 6 Ω, TTL/CMOS input compatibility, and latch-up resistance exceeding 500 mA reverse current. It is available in 8-pin PDIP, SOIC, and CERDIP packages. The temperature range varies by version: 0°C to +70°C for C versions, -40°C to +85°C for E versions, -25°C to +85°C for I versions, and -55°C to +125°C for M versions. ESD protection is rated at 2 kV.
