HEF4059B
Datasheet
General description
The HEF4059B is a divide-by-n counter which can be programmed to divide an input frequency by any number n from 3 to 15 999. The output signal is a one clock-cycle wide pulse and occurs at a rate equal to the input frequency divided by n. The single output (O) has TTL drive capability. The down counter is preset by means of 16 jam inputs (J1 to J16); continued on next page.
Features
- Small plastic SMD package
- Continuous reverse voltage: max. 35 V
- Continuous forward current: max. 100 mA
- Low diode capacitance: max. 1.2 pF
