FK PACKAGE (TOP VIEW) The 3-state outputs can interface with and drive data lines of bus-organized systems. With all but one of the common outputs disabled (at a high-impedance state), the low impedance of the single enabled output will drive the bus line to a high or low logic level. Each output has its own strobe (G) inputs. The output is disabled when its strobe is high. 4 3 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 A 2C3 NC 2C2 2C1 1Y GND NC 2Y 2C0 1C3 1C2 NC 1C1 1C0 The SN54F253 is characterized for operation over the full military temperature range of − 55°C to 125°C.
