GENERAL DESCRIPTION
Due to the use of silicon gate CMOS technology, standby current is 10 mA (max.), and power consumption is as low as 10 mA (max.) when a 5 MHz clock is generated. All items of AC characteristics are compatible with intel 8237A-5.FEATURES
● Maximum operating frequency of 5 MHz (Vcc = 5 V ± 10%)● High-speed operation at very low power consumption due to silicon gate CMOS technology
● Wide operating temperature range from –40°C to +85°C
● 4-channels independent DMA control
● DMA request masking and programming
● DMA request priority function
● DREQ and DACK input/output logic inversion
● DMA address increment/decrement selection
● Memory-to-Memory Transfers
● Channel extension by cascade connection
● DMA transfer termination by EOP input
● Intel 8237A-5 compatibility
