IDT7035S/L

High-Speed 8K x 18 Dual-Port Static RAM

Industrial and Commercial Temperature Ranges

AC Electrical Characteristics Over the

Operating Temperature and Supply VoltageRange(1,2)

Waveform of BUSY Arbitration Controlled by CE Timing(1) (M/S = VIH)

NOTES:

1. 'X' in part numbers indicates power rating (S or L).

2. Industrial temperature: for specific speeds, packages and powers contact your sales office.

Waveform of BUSY Arbitration Cycle Controlled by Address Match

Timing(1) (M/S = VIH)

NOTES:

1. All timing is the same for left and right ports. Port A may be either the left or right port. Port B is the port opposite from A.

2. If tAPS is not satisfied, the BUSY signal will be asserted on one side or another but there is no guarantee on which side BUSY will be asserted.
