CHT-CG family: Crystal Clock Generators
The CHT-CG are High Temperature Crystal Clock Generator swith added capabilities. It features a crystal oscillator driver with disable input, an ancillary clock signal input and a programmable divider chain. Using an external crystal, it is intended to provide reliable precision performance throughout the -55 to +225°C temperature range.
Typical performances:
- 3.3 to 5V Power Supply
- Temperature range: -55°C to +225°C
- Input sources: crystal or external clock
- Frequencies: DC to 50MHz
- 3-states output buffer
- Programmable output buffer
- Programmable output frequency divider
- Programmable crystal driver (CHT-CG50)
- Standby mode
- Internal passives components (CHT-CG50)

CHT-555 Timers: CHT-555 pin-to-pin compatible Timer
The CHT-555 is a high-temperature, low-power, highly stable device for generating accurate time delays or oscillations, with enhanced capabilities compared to the well known NE555.
Typical performances:
- 5V Power Supply
- Temperature range: -55°C to +225°C (operational up to 250°C)
- Timing from microsecond to hours
- Monostable and bistable mode
- Internal passive components (only CHT-555-DIL14)
