MH8807
MH8807 is oscillator/clock drivers manufactured by National Semiconductor.
description
The MH7807/MH8807 is a plete self-contained two-phase oscillators and clock driver subsystems for MOS micro-puter, calculator and shift register systems_ features
- No ext$rnal timing ponents
- Two non-overlapping outputs
- Both frequency and pulse width are voltage controlled
- Frequency adjustable from 400 k Hz to 2 MHz
- Pulse width adjustable from 300 ns to 2f.ls
- Low power for battery operation
- TTL outputs for verification and synchroniza- tion
- E!oth direct and damped MOS outputs logic diagram
