HD74HC221 Dual Monostable Multivibrators (with Schmitt Trigger Input) REJ03D0591-0200 (Previous ADE-205-468) Rev.2.00 Jan 31, 2006 Description Each multivibrator features both a negative, A, and a positive, B, transition triggered input, either of which can be used as an inhibit. Also included is a clear input that when taken low resets the one shot. The HD74HC221 can be triggered on the positive transition of the clear while A is held low and B is held high. This device is a non-retriggerable, and therefore cannot be retriggered until the output pulse times out. The output pulse equation is simply: tW = 0.7*(Rext)*(Cext) Features * * * * * * High Speed Operation High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 A max Low Quiescent Supply Current Ordering Information Part Name HD74HC221P HD74HC221FPEL Package Type DILP-16 pin SOP-16 pin (JEITA) Package Code (Previous Code) PRDP0016AE-B (DP-16FV) Package Abbreviation P -- EL (2,000 pcs/reel) Taping Abbreviation (Quantity) PRSP0016DH-B FP (FP-16DAV) Note: Please consult the sales office for the above package availability.
