CDC328AD

Overview

The CDC328AD is a fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It features a single circuit with a 1:6 input-to-output ratio, providing six TTL-compatible outputs from one TTL input. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum frequency of 100 MHz. It is housed in a 16-SOIC surface-mount package with a width of 3.90mm. The component is rated for an operating temperature range of -40°C to +85°C.
