One Chip Select plus one Output Enable pin
Inputs and outputs are LVTTL-compatible
Single 3.3V supply
Low power consumption via chip deselect
Available in a 32-pin 300- and 400-mil Plastic SOJ, and
32-pin Type II TSOP packages.
TheIDT71V124has anoutputenablepinwhichoperates as fastas
5ns, with address access times as fast as 9ns available. All bidirec-
tionalinputs andoutputs oftheIDT71V124areLVTTL-compatibleand
operation is from a single 3.3V supply. Fully static asynchronous
circuitry is used; no clocks or refreshes are required for operation.

2. All inputs switch between 0.2V (Low) and VDD–0.2V (High).
3. fMAX = 1/tRC (all address inputs are cycling at fMAX); f = 0 means no address input lines are changing.

NOTES:
1. A write occurs during the overlap of a LOW CS and a LOW WE.
2. OE is continuously HIGH. During a WE controlled write cycle with OELOW, tWP must be greater than or equal to tWHZ + tDW to allow the I/O drivers to turn off and data to be
placedonthe bus forthe requiredtDW. IfOEis HIGHduringa WE controlledwrite cycle, this requirementdoes notapplyandthe minimumwrite pulse is the specifiedtWP.
