HD74HC620, HD74HC623 Octal Bus Transceivers (with inverted 3-state outputs) Octal Bus Transceivers (with 3-state outputs) REJ03D0636-0200 (Previous ADE-205-516) Rev.2.00 Mar 30, 2006 Description This octal bus transceiver is designed for asynchronous two-way communication between data buses. The control function implementation allows for maximum flexibility in timing. This device allows data transmission from the A bus to the B bus or from the B bus to the A bus depending upon the logic levels at the enable inputs (GBA and GAB). The enable inputs can be used to disable the device so that the buses are effectively isolated. The dual-enable configuration gives these devices the capability to store data by simultaneous enabling of GBA and GAB. Each output reinforces its input in this transceiver configuration. Thus, when both control inputs are enabled and all other data sources to the two sets of bus lines are at high impedance, both sets of bus lines (16 in all) will remain at their last states. The 8-bit codes appearing on the two sets of buses will be identical for the HD74HC623 or complementary for the HD74HC620. Features • High Speed Operation: tpd (Bus to Bus) = 12 ns typ (CL = 50 pF) • High Output Current: Fanout of 15 LSTTL Loads (QA to QH outputs) • 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 Taping Abbreviation (Quantity) HD74HC620P DILP-20 pin PRDP0020AC-B (DP-20NEV) P — HD74HC620FPEL HD74HC623FPEL SOP-20 pin (JEITA) PRSP0020DD-B (FP-20DAV) FP EL (2,000 pcs/reel) HD74HC620RPEL HD74HC623RPEL SOP-20 pin (JEDEC) PRSP0020DC-A (FP-20DBV) RP EL (1,000 pcs/reel) Note: Please consult the sales office for the above package availability.
