MC5474F373 Datasheet, PDF (1/3 Pages) Motorola, Inc – OCTAL TRANSPARENT LATCH WITH 3-STATE OUTPUTS

OCTAL TRANSPARENT LATCH
WITH 3-STATE OUTPUTS
The MC54/74F373 consists of eight latches with 3-state outputs for bus or-
ganized 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.
• Eight Latches in a Single Package
• 3-State Outputs for Bus Interfacing
• ESD ^> 4000 Volts
