HD74HC253 Dual 4-to-1-line Data Selectors/Multiplexers (with 3-state outputs) REJ03D0600–0200 (Previous ADE-205-477) Rev.2.00 Jan 31, 2006 Description The large output drive and 3-state features of this device make it ideally suited for interfacing with bus lines in bus organized systems. When the output control input is taken high, the multiplexer outputs are sent into a high impedance state. When the output control is held low, the associated multiplexer chooses the correct output channel for .

HD74HC253 Dual 4-to-1-line Data Selectors/Multiplexers (with 3-state outputs) REJ03D0600–0200 (Previous ADE-205-477) Rev.2.00 Jan 31, 2006 Description The large output drive and 3-state features of this device make it ideally suited for interfacing with bus lines in bus organized systems. When the output control input is taken high, the multiplexer outputs are sent into a high impedance state. When the output control is held low, the associated multiplexer chooses the correct output channel for the given input signals determined by the select A and B inputs. Features • High Speed Operation: tpd (Data to Y) = 18 ns typ (CL = 50 pF) • High Output Current: Fanout of 10 LSTTL Loads • Wide Operating Voltage: VCC = 2 to 6 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) • Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation HD74HC253P DILP-16 pin PRDP0016AE-B (DP-16FV) P .
