cdc337 is a single clock input, eight-way clock output clock driver with low output skew and low pulse skew launched by texas instruments, which can simultaneously output clock frequency and one-half of the clock frequency.
The CDC337 is an EPIC-IIB BiCMOS device featuring four same-frequency outputs (Y) and four half-frequency outputs (Q). It includes TTL-compatible inputs and CMOS-compatible outputs, driven by a single clock input. The chip supports distributed Vcc and ground pins to reduce switching noise and offers high-drive capabilities of ±48 mA.
| Supply Voltage Range | -0.5V to 7V (Absolute Max) |
|---|---|
| Operating Temperature Range | -40°C to 85°C |
| High-Level Output Current | -48 mA |
| Low-Level Output Current | 48 mA |
| Maximum Clock Frequency | 80 MHz |
The four Y outputs switch at the same frequency as the CLK input, while the four Q outputs toggle at one-half the clock frequency.
When the OE input is high, all outputs enter a high-impedance state.
Taking CLR low asynchronously resets all Q outputs to the low level.
