A TTL/CMOS input voltage level is translated Reverse Current into a rail-to-rail output voltage level swing. The CMOS ESD Protected: 2 kV output is within 25 mV of ground or positive supply. The low-impedance, high-current driver outputs swing Applications: a 1000 pF load 18V in 30 nsec. The unique current and Switch Mode Power Supplies voltage drive qualities make the TC426/TC427/TC428 ideal power MOSFET drivers, line drivers, and DC-to- Pulse Transformer Drive DC converter building blocks. Clock Line Driver Coax Cable Driver Input logic signals may equal the power supply voltage. Input current is a low 1 A, making direct interface toCMOS/bipolar switch-mode power supply control Device Selection Table ICs possible, as well as open-collector analog Part Temp. Package Configuration comparators. Number Range Quiescent power supply current is 8 mA maximum. The TC426COA 8-Pin SOIC Inverting 0C to +70C TC426CPA 8-Pin PDIP Inverting 0C to +70C TC426 requires 1/5 the current of the pin-compatible TC426EOA 8-Pin SOIC Inverting -40C to +85C bipolar DS0026 device. This is important in DC-to-DC TC426EPA 8-Pin PDIP Inverting -40C to +85C converter applications with power efficiency constraints TC426IJA 8-Pin CERDIP Inverting -25C to +85C TC426MJA 8-Pin CERDIP Inverting -55C to +125C and high-frequency switch-mode power supply TC427COA 8-Pin SOIC Noninverting 0C to +70C applications. Quiescent current is typically 6 mA when TC427CPA 8-Pin PDIP Noninverting 0C to +70C driving a 1000 pF load 18V at 100 kHz. TC427EOA 8-Pin SOIC Noninverting -40C to +85C TC427EPA 8-Pin PDIP Noninverting -40C to +85C The inverting TC426 driver is pin-compatible with the TC427IJA 8-Pin CERDIP Noninverting -25C to +85C bipolar DS0026 and MMH0026 devices. The TC427 is TC427MJA 8-Pin CERDIP Noninverting -55C to +125C noninverting the TC428 contains an inverting and non- TC428COA 8-Pin SOIC Complementary 0C to +70C TC428CPA 8-Pin PDIP Complementary 0C to +70C inverting driver.
