MH7807/MH8807 oscillator/clock drivers
general description
The MH7807/MH8807 is a complete self-contained two-phase oscillators and clock driver subsystems for MOS micro-computer, calculator and shift register systems_
features
• No ext$rnal timing components • Two non-overlapping outputs • Both frequency and pulse width are voltage
controlled
• Frequency adjustable from 400 kHz 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
