VCC OE1 1 20 A0 2 19 OE2 A1 3 18 Y0 The Intersil HCTS540MS is a Radiation Hardened inverting
Octal Buffer/Line Driver, with two active-low output enables.
The output enable pins (OE1 and OE2) control the threestate outputs. If either enable is high the outputs will be in the
high impedance state. For data output both enables (OE1
and OE2) must be low. A2 4 17 Y1 A3 5 16 Y2 A4 6 15 Y3 A5 7 14 Y4 A6 8 13 Y5 A7 9 12 Y6 The HCTS540MS utilizes advanced CMOS/SOS technology
to achieve high-speed operation. This device is a member of
radiation hardened, high-speed, CMOS/SOS Logic Family. GND 10 11 Y7 Description The HCTS540MS is supplied in a 20 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix). Ordering Information
