MSM82C84A-2RS/GS/JS
CLOCK GENERATOR AND DRIVER
GENERAL DESCRIPTION
The MSM82C84A-2RS/GS is a clock generator designed to generate MSM80C86A-10 and
MSM80C88A-10 system clocks of 8MHz.
Due to the use of silicon gate CMOS technology, standby current is only 40 mA (MAX.), and the
power consumption is very low with 16 mA (MAX.) when a 8 MHz clock is generated.
FEATURES
• Operating frequency of 6 to 24 MHz (CLK output 2 to 8 MHz)
• 3 m silicon gate CMOS technology for low power consumption
• Built-in crystal oscillator circuit
• 3 V to 6 V single power supply
• Built-in synchronized circuit for MSM80C86A-10 and MSM80C88A-10 READY and RESET
• TTL compatible
• Built-in Schmitt trigger circuit (RES input)
• 18-pin Plastic DIP (DIP18-P-300-2.54): (Product name: MSM82C84A-2RS)
• 20-pin Plastic QFJ (QFJ20-P-S350-1.27): (Product name: MSM82C84A-2JS)
• 24-pin Plastic SOP (SOP24-P-430-1.27-K): (Product name: MSM82C84A-2GS-K)
