74HCT9046A
General description
The 74HCT9046A is a high-speed Si-gate CMOS device. It is specified in compliance with JEDEC standard no 7A.
Features
- Operation power supply voltage range from 4.5 to 5.5 V
- Low power consumption
- Inhibit control for ON/OFF keying and for low standby power consumption
- Centre frequency up to 17 MHz (typical) at VCC = 5.5 V
- Choice of two phase comparators:
- PC1: EXCLUSIVE-OR
- PC2: Edge-triggered JK flip-flop.
- No dead zone of PC2
- Charge pump output on PC2, whose current is set by an external resistor Rb
- Centre frequency tolerance +-10pct
- Excellent Voltage Controlled Oscillator (VCO) linearity
- Low frequency drift with supply voltage and temperature variations
- On-chip band gap reference
- Glitch free operation of VCO, even at very low frequencies
- Zero voltage offset due to op-amp buffering
- ESD protection:
- HBM EIA/JESD22-A114-A exceeds 2000 V
- MM EIA/JESD22-A115-A exceeds 200 V.
