HD74HC442, HD74HC443, HD74HC444 Quad. Tridirectional Bus Transceiver (with noninverted 3-state outputs) Quad. Tridirectional Bus Transceiver (with inverted 3-state outputs) Quad Tridirectional Bus Transceiver (with noninverted/inverted 3-state outputs) REJ03D0627-0200 (Previous ADE-205-506) Rev.2.00 Mar 30, 2006 Description These bus transceivers are designed for a synchronous three-way communication between four-line data buses. They give the designer a choice of selecting inverting, noninverting or a combination of inverting and noninverting data paths with 3-state outputs. The S0 and S1 inputs select the bus from which data are to be transferred. The G inputs enable the bus or buses to which data are to be transferred. The port for any bus selected for input and any other bus not enabled for output will be at high impedance. Features • High Speed Operation • High Output Current: Fanout of 15 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 HD74HC442RPEL HD74HC443RPEL HD74HC444RPEL Package Type SOP-20 pin (JEDEC) Rev.2.00 Mar 30, 2006 page 1 of 7 Package Code (Previous Code) PRSP0020DC-A (FP-20DBV) Package Abbreviation RP Taping Abbreviation (Quantity) EL (1,000 pcs/reel) HD74HC442, HD74HC443, HD74HC444 Function Table Inputs Transfers Between Buses CS H S1 X S0 X GA X GB X GC X HD74HC442 None HD74HC443 None HD74HC444 None X X H X H X X H X H X H None None None None None None X X L L L H X H H X H H None None None None None None X L H L L L H X H L X L None A → B, A → C None A → B, A → C None A → B, A → C L L L H H L L L X L L X B → C, B → A C → A, C → B B → C, B → A C → A, C → B B → C, B → A C → A, C → B L L L L L H X H L X H L A→B B→C A→B B→C A→B B→C L L H L L L L X H H X L C→A A→C C→A A→C C→A A→C L L L H H L L H X L H X B→A C→B B→A C→B B→A C→B H : L : X : high level low level irrelevant Pin Arrangement CS 1 20 VCC B1 2 19 GC C1 3 18 GB C2 4 17 GA B2 5 16 A1 B3 6 15 A2 C3 7 14 A3 C4 8 13 A4 B4 9 12 S1 GND 10 11 S0 (Top view) Rev.2.00 Mar 30, 2006 page 2 of 7 HD74HC442, HD74HC443, HD74HC444 Logic Diagram HD74HC442 S0 S1 A1 B1 C1 A2 B2 C2 A3 B3 C3 A4 B4 C4 Rev.2.00 Mar 30, 2006 page 3 of 7 GA GB GC CS HD74HC442, HD74HC443, HD74HC444 HD74HC443 S0 S1 A1 B1 C1 A2 B2 C2 A3 B3 C3 A4 B4 C4 Rev.2.00 Mar 30, 2006 page 4 of 7 GA GB GC CS HD74HC442, HD74HC443, HD74HC444 HD74HC444 S0 S1 A1 B1 C1 A2 B2 C2 A3 B3 C3 A4 B4 C4 Rev.2.00 Mar 30, 2006 page 5 of 7 GA GB GC CS HD74HC442, HD74HC443, HD74HC444 Absolute Maximum Ratings Item Symbol Ratings Unit Supply voltage range Input / Output voltage VCC VIN, VOUT –0.5 to 7.0 –0.5 to VCC +0.5 V V IIK, IOK IO ±20 ±35 mA mA ICC or IGND PT ±75 500 mA mW Input / Output diode current Output current VCC, GND current Power dissipation Storage temperature Tstg –65 to +150 °C Note: The absolute maximum ratings are values, which must not individually be exceeded, and furthermore, no two of which may be realized at the same time.
