FUNCTIONAL DESCRIPTION
PIN DESCRIPTIONS
The PDU18F-series device is a 8-bit digitally programmable delay line.
IN Delay Line Input
The delay, TDA, from the input pin (IN) to the output pins (OUT, OUT/)
depends on the address code (A7-A0) according to the following formula:
OUT Non-inverted Output
OUT/ Inverted Output
A0-A7 Address Bits
TDA = TD0 + TINC * A
EN/ Output Enable
VCC +5 Volts
where A is the address code, TINC is the incremental delay of the device,
GND Ground
and TD0 is the inherent delay of the device. The incremental delay is
specified by the dash number of the device and can range from 0.5ns through 10ns, inclusively. The
enable pins (EN/) are held LOW during normal operation. These pins must always be in the same state
and may be tied together externally. When these signals are brought HIGH, OUT and OUT/ are forced into
LOW and HIGH states, respectively. The address is not latched and must remain asserted during normal
operation.
SERIES SPECIFICATIONS
• Programmed delay tolerance: 5% or 2ns,
whichever is greater
• Inherent delay (TD0): 13ns typical (OUT)
12ns typical (OUT/)
• Setup time and propagation delay:
Address to input setup (TAIS): 10ns
Disable to output delay (TDISO): 6ns typ. (OUT)
• Operating temperature: 0° to 70° C
• Temperature coefficient: 100PPM/°C (excludes TD0)
• Supply voltage VCC: 5VDC ± 5%
• Supply current: ICCH = 65ma
ICCL = 128ma
• Minimum pulse width: 6% of total delay
