The delay, TDA, from the input pin (IN) to the output pins (OUT, OUT/) depends on the address code (A3-A0) according to the following formula: TDA = TD0 + TINC - A PIN DESCRIPTIONS IN OUT OUT/ A0-A3 EN/ VCC GND Delay Line Input Non-inverted Output Inverted Output Address Bits Output Enable +5 Volts Ground where A is the address code, TINC is the incremental delay of the device, 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 100ns, 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.
