P4C198L-15LI Datasheet PDF - Performance Semiconductor

●DESCRIPTION

●The P4C198/L and P4C198A/L are 65,536-bit ultra high speed static RAMs organized as 16K x 4. Each device features an active low Output Enable control to eliminate data bus contention. The P4C198/L also have an active low Chip Enable (the P4C198A/L have two Chip Enables, both active low) for easy system expansion. The CMOS memories require no clocks or refreshing and have equal access and cycle times. Inputs are fully TTL-compatible. The RAMs operate from a single 5V ± 10% tolerance power supply. Data integrity is maintained with supply voltages down to 2.0V. Current drain is typically 10 µA from a 2.0V supply.
