VT7203

The VT7203 is designed an first-in, first-out (FIFO) memory that uses a high performance static RAM array with internal logic to ensure totally asynchronous operation. Full, half-full and empty flags are provided to allow the device to operate without enternal logic.

VT7203 has eleven features. (1)First-in, first-out dual-port memory. (2)Low power CMOS process. (3)Fully asynchronous operation. (4)Simultaneous read and write. (5)Full expandable in depth and width. (6)Access time 20ns. (7)Dependable empty, half-full, and full warning flags. (8)Rate buffer applications. (9)Multi-processing master/slave applications. (10)28-lead, 600mil plastic DIP. (11)32-lead PLCC. Those are all the main features.

Some absolute maximum ratings of VT7203 have been concluded into several points as follow. (1)Its storage temperature range would be from -65°C to 150°C. (2)Its voltage on any terminal relative to ground would be from -0.5V to 7.0V. (3)Its applied output voltage would be from -0.5V to 7.0V. (4)Its applied input voltage would be from -0.5V to 7.0V. (5)Its short circuit current would be 30mA. (6)Its power dissipation would be 1W. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of VT7203 are concluded as follow. (1)Its input high voltage would be min 2.2V and max Vcc+1V. (2)Its input low voltage would be min -1.0V and max 0.8V. (3)Its output high voltage would be min 2.4V. (4)Its output low voltage would be max 0.4V. (5)Its input leakage current any input would be min -1uA and max 1uA. (6)Its output leakage current would be min -10uA and max 10uA. (7)Its power supply current would be max 80mA average operating current and would be max 8mA at R=W=RS=FL=Vih. (8)Its syandby current would be max 5mA. (9)Its input capacitance would be typ 7pF and max 10pF. (10)Its output capacitance would be typ 8pF and max 10pF. And so on.
