High-Speed 4K x 8 Dual-Port Static RAM with Semaphore

Industrial and Commercial Temperature Ranges

Absolute Maximum Ratings(1)

Capacitance(1) (TA = +25°C, f = 1.0MHz)

Maximum Operating

Temperature and Supply Voltage(1,2)

Recommended DC Operating

Conditions

NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may

cause permanent damage to the device. This is a stress rating only and functional

operation of the device at these or any other conditions above those indicated in the

operational sections of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect reliability.

2. VTERM must not exceed Vcc + 10% for more than 25% of the cycle time or 10 ns

maximum, and is limited to < 20mA for the period of VTERM > Vcc +10%.

NOTES:

1. This parameter is determined by device characterization but is not production

tested.

2. 3dv references the interpolated capacitance when the input and output signals

switch from 0V to 3V and from 3V to 0V.

NOTES:

1. This is the parameter TA. This is the "instant on" case temperature.

NOTES:

1. VIL (min.) > -1.5V for pulse width less than 10ns.

2. VTERM must not exceed Vcc + 10%.

NOTE:

1. At Vcc < 2.0V input leakages are undefined.
