HEF4060BT.653, Программируемый делитель частоты [SO16]
The HEF4060BT is a 14-stage Ripple-Carry Binary Counter/Divider and Oscillator with three oscillator terminals (RS, REXT and CEXT), ten buffered outputs (Q3 to Q9 and Q11 to Q13) and an overriding asynchronous master reset input (MR). The oscillator configuration allows design of either RC or crystal oscillator circuits. The oscillator may be replaced by an external clock signal at input RS. The clock input's Schmitt-trigger action makes it highly tolerant to slower clock rise and fall times. The counter advances on the negative-going transition of RS. A high level on MR resets the counter (Q3 to Q9 and Q11 to Q13 = low), independent of other input conditions. It operates over a recommended VDD power supply range of 3 to 15V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS or another input.
• Tolerant of slow clock rise and fall time
• Fully static operation
• Standardized symmetrical output characteristics
• Inputs and outputs are protected against electrostatic effects
• Complies with JEDEC standard JESD 13-B
