__F ast Logic Programmable Delay Units (6-Bit) TTL interfaced SERIES: PDU-16F Features: @ Input & Output TTL buffered a 6-Bit TTL programmable delay line @ Two (2) Separate outputs; inverting and non-inverting. = Completely interfaced m@ Compact & low profile Specifications: m= Propagation delay: Address to output (Tsua) = 7 ns typ. Enable to output (Tsue) = 6 ns typ. mg Delay variation: Monotonic in one direction. mg Programmed delay tolerance: +5% or 2 ns whichever is greater. inherent delay (Too): 9 ns on pin typical 8 ns on pin 1 Supply veltage: 5 Vdc + 5%. Operating temperature: 0-70" C. Temperature coefficient: 100 PPM/C. Supply current: IccH = 74 ma. IccL = 30 ma. Minimum pulse-width = 10% of total delay. DC parameters: See TTL-Fast Schottky Logic Table on Page 6.
