1 / 16 page CDC208 DUAL 1LINE TO 4LINE CLOCK DRIVER WITH 3STATE OUTPUTS SCAS109F − APRIL 1990 − REVISED OCTOBER 1998 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Low-Skew Propagation Delay Specifications for Clock-Driver Applications D TTL-Compatible Inputs and CMOS-Compatible Outputs D Flow-Through Architecture Optimizes PCB Layout D Center-Pin VCC and GND Pin Configurations Minimize High-Speed Switching Noise D EPIC (Enhanced-Performance Implanted CMOS) 1- µm Process D 500-mA Typical Latch-Up Immunity at 125 °C D Package Options Include Plastic Small-Outline (DW) description The CDC208 contains dual clock-driver circuits that fanout one input signal to four outputs with minimum skew for clock distribution (see Figure 2). The device also offers two output-enable (OE1 and OE2) inputs for each circuit that can force the outputs to be disabled to a high-impedance state or to a high- or low-logic level independent of the signal on the respective A input. Skew parameters are specified for a reduced temperature and voltage range common to many applications. The CDC208 is characterized for operation from − 40 °C to 85°C.
