Description
The Intersil 82C83H is a high performance CMOS Octal
Latching Buffer manufactured using a self-aligned silicon gate
CMOS process (Scaled SAJI IV). The 82C83H provides an 8-
bit parallel latch/buffer in a 20 lead pin package. The active
high strobe (STB) input allows transparent transfer of data
and latches data on the negative transition of this signal. The
active low output enable (OE) permits simple interface to
microprocessor systems. The 82C83H provides inverted data
at the outputs.
