thru A8 become inputs and the B1 thru B8 become outputs. When
the GAB and GBA are held low, the A1 thru A8 become output
and the B1 thru B8 become inputs. When GAB is low and GBA
is high, the outputs functions of the A and B Busses are disabled.
CBA clock inputs, respectively.
Features (Note 1) (Note 2)
The TC74HC652A is high speed CMOS OCTAL BUS
It achieves the high speed operation similar to equivalent
This device is bus transceiver with 3-state outputs, D-type
When the enable input GAB and GBA are held high, the A1
The select inputs (SAB, SBA) can multiplex sort and real-time (transparent mode) data.
Data on the A Bus or B Bus can be clocked into the registers on the positive going transition of either CAB or
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
High speed: f
Low power dissipation: I
High noise immunity: V
Output drive capability: 15 LSTTL loads
Symmetrical output impedance: |I
Balanced propagation delays: t
Wide operating voltage range: V
Pin and function compatible with 74LS652
Note 1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.
Note 2: All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull
down resistors.
