(DMOS) transistors with output voltage ratings of _ NC-Nointemal connection 70 V and 40-mA source-current capability. All inputs are compatible with CMOS and TTL levels, but each requires the addition of a pullup resistor to Voo1 when driven by TTL logic. The TL4810B is characterized for operation from 0°C to 70°C. The TL4810BI is characterized for operation from -—40°C to 85°C. +BIDFET - Bipolar, double-diffused, N-channel and P-channel MOS transistors on same chip. This is a patented process.
