74F399 General Description
The 74F398 and 74F399 are the logical equivalents of a quad 2-input multiplexer feeding into four edge-triggered flip-flops. A common Select input determines which of the two 4-bit words is accepted. The selected data enters the flip-flops on the rising edge of the clock. The 74F399 is the 16-pin version of the 74F398, with only the Q outputs of the flip-flops available.

Storage Temperature -65°C to +150°C
Ambient Temperature under Bias -55°C to +125°C
Junction Temperature under Bias -55°C to +175°C
Plastic -55°C to +150°C
VCC Pin Potential to
Ground Pin -0.5V to +7.0V
Input Voltage (Note 2) -0.5V to +7.0V
Input Current (Note 2) -30 mA to +5.0 mA
Voltage Applied to Output
