TBP28

The TBP28 of monolithic TTL programmable read-only memories (PROMs) feature an expanded selection of standard and low-power PROMs.This expanded PROM family provides the system designer with considerable flexibility in upgrading existing designeds or optimizing new designs.

Features of the TBP28 are:(1)expanded family of standard and low power PROMs;(2)titanium tungsten (Ti-W) fuse links for reliable low-voltage full-family-compatible programming;(3)full decoding and fast chip select simplify system design;(4)P-N-P inputs for reduced loading on system buffers/drivers;(5)each PROM supplied with a high logic level stored at each bit location;(6)application include.

The absolute maximum ratings of the TBP28 can be summarized as:(1):the parameter is supply voltage,the rating is 7,the unit is V;(2):the parameter is input voltage,the rating is 5.5,the unit is V;(3):the parameter is chip-select peak input voltage,the rating is 11,the unit is V;(4):the parameter is off-state output voltage,the rating is 5.5,the unit is V;(5):the parameter is off-state peak output voltage,the rating is 16.25,the unit is V;(6):the parameter is operating free-air temperature range:full-temperature-range circuits,the rating is -55 to 125,the unit is ;(7):the parameter is operating free-air temperature range:commercial-temperature-range circuits,the rating is 0 to 70,the unit is ;(8):the parameter is storage temperature range,the rating is -65 to 150,the unit is .
