74HCT7046A Description
The 74HC/HCT7046 are high-speed Si-gate CMOS devices and are specified in pliance with JEDEC standard no. The 74HC/HCT7046 are phase-locked-loop circuits that prise a linear voltage-controlled oscillator (VCO) and two different phase parators (PC1 and PC2) with a mon signal input amplifier and a mon parator input. A lock detector is provided and this gives a HIGH level at pin 1 (LD) when the PLL is locked.
