AT27BV5122Atmel’s innovative design techniques provide fast speedsthat rival 5V parts while keeping the low power consump-tion of a 3V supply. At VCC
AT27BV5123Note: 1. Minimum voltage is -0.6V dc which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is VCC + 0.75V
AT27BV5124Notes: 1. VCC must be applied simultaneously with or before OE/VPP, and removed simultaneously with or after OE/VPP.2. VPP may be connected
AT27BV5125AC Waveforms for Read Operation(1)Notes: 1. Timing measurement references are 0.8V and 2.0V. Input AC drive levels are 0.45V and 2.4V, unles
