74F373 Octal Transparent Latch with 3-STATE Outputs
General Description
The 74F373 consists of eight latches with 3-STATE outputs for bus organized system applications. The flip-flops appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup times is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH the bus output is in the high impedance state.
Features
s Eight latches in a single package s 3-STATE outputs for bus interfacing s Guaranteed 4000V minimum ESD protection
