The A3 5 16 Y2 output enable pins (OEN1 and OEN2) control the three-state outputs. If either enable is high the outputs will be in the high A4 6 15 Y3 impedance state. For data output both enables (OEN1 and A5 7 14 Y4 OEN2) must be low. A6 8 13 Y5 A7 9 12 Y6 The HCTS541MS utilizes advanced CMOS/SOS technology GND 10 11 Y7 to achieve high-speed operation. This device is a member of radiation hardened, high-speed, CMOS/SOS Logic Family. The HCTS54 is supplied in a 20 lead Ceramic flatpack (K suffix) or a SBDIP Package (D suffix).
