The LP3990 is a 150mA linear voltage regulator designed for portable, battery-powered systems providing an accurate output voltage, low noise, and low quiescent current. The LP3990 will provide a 0.8V output from the low input voltage of 2V at up to 150mA load current. When switched into shutdown mode via a logic signal at the enable pin, the power consumption is reduced to virtually zero. The LP3990 is designed to be stable with space saving ceramic capacitors as small as 0.47µF. Performance is specified for a -40˚C to 125˚C junction tem- perature range. For output voltages other than 0.8V, 1.35V, 1.5V, 1.8V, 2.5V, 2.8V, or 3.3V please contact your local NSC sales office.

This is a data sheet for MV54ACT257-X, which introduces the features of the product, including multiplexer expansion, non-inverting tri-state outputs, output source/sink 24 mA, etc.

MN54F189-X REV 1A0 is a 64-bit random access memory with 3-state outputs. The memory is organized as a 16-word by 4-bit array, address inputs are buffered to minimize loading and are fully decoded on-chip. Outputs are 3-state and are in the high impedance state whenever the Chip Select (CS) input is HIGH. Outputs are active only in the Read mode and the output data is the complement of the stored data.

The 'FCT541 is an octal buffer and line driver with TRI-STATE outputs designed to be employed as a memory and address driver, clock driver, or bus-oriented transmitter/receiver. The 'FCT541 is similar to the 'FCT244 with broadside pinout.
