Description

The MC54/ 74HC393 is identical in pinout to the LS393. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible a 74HCTOO quad NAND gate, and a 74HC393 counter on the board to provide clocking and conversion control signals for the MAX176. Figures 1 and 2 1 Abstract. The 16 MHz Crystal Oscillator module is designed to handle off-chip crystals that have a frequency of. 4 16 MHz. The crystal oscillators output is fed A clock receives an input frequency from a source and either distributes that frequency or generates new frequencies to send as outputs to other devices within DESCRIPTION. The M74HC393 is an high speed CMOS DUAL. BINARY COUNTER fabricated with silicon gate. C2MOS technology. This counter circuit
