主要参数

The 74HC4046A; 74HCT4046A is a high-speed Si-gate CMOS device. It is specified in compliance with JEDEC standard no 7A.

特性

  • Low power consumption

  • VCO-Inhibit control for ON/OFF keying and for low standby power consumption

  • Centre frequency of up to 17 MHz (typical) at VCC = 4.5 V

  • Choice of three phase comparators:

    • PC1: EXCLUSIVE-OR

    • PC2: Edge-triggered JK flip-flop

    • PC3: Edge-triggered RS flip-flop

  • Excellent Voltage Controlled Oscillator (VCO) frequency linearity

  • VCO-inhibit control for ON/OFF keying and for low standby power consumption

  • Low frequency drift with supply voltage and temperature variations

  • Operating power supply voltage range:

    • VCO section 3.0 V to 6.0 V

    • Digital section 2.0 V to 6.0 V

  • Zero voltage offset due to operational amplifier buffering

  • ESD protection:

    • HBM JESD22-A114F exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V


目标应用

  • FM modulation and demodulation

  • Frequency synthesis and multiplication

  • Frequency discrimination

  • Tone decoding

  • Data synchronization and conditioning

  • Voltage-to-frequency conversion

  • Motor-speed control
