GENERAL DESCRIPTION

The TDF8704T is an 8-bit high-speed analog-to-digital

converter (ADC) for general industrial applications. It

converts the analog input signal into 8-bit binary-coded

digital words at a maximum sampling rate of 50 MHz. All

digital inputs and outputs are TTL compatible, although a

low-level AC clock input signal is allowed.
