CHIP DATA

	The CD 4510 is a BCD (Binary Coded Decimal) up/down counter. The chip counts in binary to 15 and resets. This gives it a count-of-16 (0000 to 1111). It has 4 presets (P1, P2, P3 and P4) that can be preset by taking them HIGH. If P2 and P3 are taken high, the counter will start at 0110 and count up (or down, according to the voltage on pin 10) and "cycle" on each ten counts.
	The CD 4510 is a CMOS chip. Minimum supply voltage 6v Maximum supply voltage 15v Max current per output 15mA Maximum speed of operation 5MHz When the Reset line is taken HIGH, all outputs become LOW (and any preset value is delivered to the output when the reset line goes low).
