74F794 8-Bit Register with Readback March 1990 Revised August 1999 74F794 8-Bit Register with Readback General Description The 74F794 is an 8-bit register with readback capability designed to store data as well as read the register information back onto the data bus. The I/O bus (D bus) has 3STATE outputs. Current sinking capability is 64 mA on both the D and Q busses. Data is loaded into the registers on the LOW-to-HIGH transition of the clock (CP). The output enable (OE) is used to enable data on D0–D7. When OE is LOW, the output of the registers is enabled on D0–D7, enabling D as an output bus. When OE is HIGH, D0–D7 are inputs to the registers configuring D as an input bus.
