TX-2B

The TX-2B is a kind of CMOS LSI designed for remote controlled car applications. The TX-2B device has five control keys for controlling the motions (i.e. forward, backforward, rightward, leftward and the turbo function) of the remote controlled car. There are some features as follows: (1)wide operating voltage range (VCC=1.5 to 5.0 V); (2)low stand-by current; (3)few components are needed; (4)auto-power-off function for TX-2B.

What comes next is about the absolute maximum ratings of TX-2B: (1)supply voltage, VDD: 0.3 to 0.5 V; (2)input/output voltage, VIN. VOUT; GND-0.3 to VDD+0.3 V; (3)operating temperature, Topr: -10 to 65; (4)storage temperature, Tstg: -25 to 125.

The following is about the electrical characteristics of TX-2B (VDD=4.0 V, FOSC=128 kHz, Tamb=25, unless otherwise noted): (1)operating voltage, VDD: 1.5 V min, 4.0 V typ and 5.0 V max; (2)operating current, IDD: 2.0 mA max; (3)stand-by current, ISTB: 10A max; (4)DC O/P driving current, Idrive: 5 mA min; (5)AC O/P driving current, Idrive: 5 mA min; (6)AC O/P frequency, Faudio: 0.5 kHz min and 1.0 kHz max.
