Notes :
5. Vcc = 5.5 V, Vin = Gnd to Vcc, CS = VIH, Vout = 0 to Vcc.
6. VIH max = Vcc + 0.3 V, VIL min = –0.3 V or –1 V pulse width 50 ns.
7. Vcc min, IOL = 4 mA, IOH = –4 mA.
Data-Retention Mode
MHS CMOS RAMs are designed with battery backup in
mind. Data retention voltage and supply current are
guaranteed over temperature. The following rules insure
data retention :
1 – Chip select (CS) must be held high during data
retention ; within VCC to VCC – 0.2 V.
2 – CS must be kept between VCC – 0.2 V and 70 % of VCC
during the power up and power down transitions.
3 – The RAM can begin operation > tRC after VCC
reaches the minimum operating voltage (4.5 volts).
