philips semiconductors product specification 74f620/74F623 transceivers 74f620 octal bus transceiver, inverting (3-state) 74F623 octal bus transceiver, non-inverting (3-state) 2 1990 apr 6 8530379 96249 features ? high-impedance npn base inputs for reduced loading (70 m a in high and low states) ? ideal for applications which require high output drive and minimal bus loading ? octal bidirectional bus interface ? 3-state buffer outputs sink 64ma and source 15ma ? 74f620, inverting ? 74F623, non-inverting description the 74f620 is an octal transceiver featuring inverting 3-state bus-compatible outputs in both send and receive directions. the outputs are capable of sinking 64ma and sourcing up to 15ma, providing very good capacitive drive characteristics. the 74F623 is a non-inverting version of the 74f620. these octal bus transceivers are designed for asynchronous two-way communication between data buses. the control function implementation allows for maximum flexibility in timing. these devices allow 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 (oeba and oeab). the enable inputs can be used to disable the device so that the buses are effectively isolated. the dual-enable configuration gives the 74f620 and 74F623 the capability to store data by the simultaneous enabling of oeba and oeab. 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 the bus lines are at high impedance, both sets of bus lines (16 in all) will remain in their last states. type typical propagation delay typical supply current (total) 74f620 3.5ns 80ma 74F623 4.5ns 105ma ordering information description commercial range v cc = 5v 10%, t amb = 0 c to +70 c pkg dwg # 20-pin plastic dip n74f620n, n74623n sot146-1 20-pin plastic sol n74f620d, n74623d sot163-1 input and output loading and fan-out table pins description 74f(u.l.) high/low load value high/low a0 - a7, b0 - b7 data inputs 3.5/1.16 70 m a/70 m a oeba , oeab output enable inputs 1.0/0.033 20 m a/20 m a a0 - a7 data outputs 150/40 3ma/24ma b0 - b7 data outputs 750/106.7 15ma/64ma note: one (1.0) fast unit load is defined as: 20 m a in the high state and 0.6ma in the low state. pin configuration 74f620 20 19 18 17 16 15 14 13 12 10 11 9 8 7 6 5 4 3 2 1 v cc b1 b2 b3 b4 b5 b6 b7 oeab a1 a2 a3 a4 a5 a6 a7 gnd oeba a0 b0 sf01124 pin configuration 74F623 20 19 18 17 16 15 14 13 12 10 11 9 8 7 6 5 4 3 2 1 v cc b1 b2 b3 b4 b5 b6 b7 oeab a1 a2 a3 a4 a5 a6 a7 gnd oeba a0 b0 sf01124
