AT27C8002bits. It requires a single 5V power supply in normal readmode operation. Any word can be accessed in less than 90ns, eliminating the need for

AT27C8003Note: 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 D

AT27C8004Notes: 1. VCC must be applied simultaneously or before VPP, and removed simultaneously or after VPP. 2. VPP may be connected directly to VCC
