Bipolar voltage amplifier Q1 translates TTL output swing of 0.4 to 2.4 V from 7400 interface to 15V drive signal for S55V01 VMOS peripheral driver. Circuit can be driven by any low-level signal, including ECL, if comparator such as AM686 is used in place of SN7400 quad NAND gate.Switching times of circuit are less than 40 ns in both directions.-L. Shaeffer, VMOS Peripheral Drivers Solve High Power Load Interface Problems, ComputerDesign, Doc. 1977, p 90, 94, and 96-98.
