When CLK is at either the high • ESD Protection Exceeds JESD 22 or low level, the D input has no effect at the output. – 2000-V Human-Body Model (A114-A) – 1000-V Charged-Device Model (C101) Device Information(1) • On Products Compliant to MIL-PRF-38535, PART NUMBER PACKAGE BODY SIZE (NOM) All Parameters Are Tested Unless Otherwise PDIP (20) 24.33 mm × 6.35 mm Noted.
