TOSHIBA TC74HC652AP_07

TC74HC652AP
TOSHIBA CMOS Digital Integrated Circuit
Silicon Monolithic
TC74HC652AP
Octal Bus Transceiver/Register (3-state)
The TC74HC652A is high speed CMOS OCTAL BUS
TRANSCEIVER/REGISTER fabricated with silicon gate CMOS
technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
This device is bus transceiver with 3-state outputs, D-type
flip-flops, and control circuitry arranged for multiplexed
transmission of data directly from the internal registers.
When the enable input GAB and GBA are held high, the A1
thru A8 become inputs and the B1 thru B8 become outputs. When
Weight
: 1.50 g (typ.)
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.
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
CBA clock inputs, respectively.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features (Note 1) (Note 2)

•
High noise immunity: VNIH = VNIL = 28% VCC (min)
•
Output drive capability: 15 LSTTL loads
•
•
Symmetrical output impedance: |IOH| = IOL = 6 mA (min)
∼ tpHL
Balanced propagation delays: tpLH −
•

•
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.

Function
The output functions of A and B busses are
disabled.
Both A and B busses are used as inputs to the
internal flip-flops. Data on the Bus will be stored
on the rising edge of the clock.
The data on the B bus are displayed on the A bus.
The data on the B bus are displayed on the A bus,
and are stored into the B storage flip-flops on the
rising edge of CBA.
The data in the B storage flip-flops are displayed
on the A bus.
The data on the B bus are stored into the B
storage flip-flops on the rising edge of CBA, and
the stored data propagate directly onto the A bus.
The data on the A bus are displayed on the B bus.
The data on the A bus are displayed on the B bus,
and are stored into the A storage flip-flops on the
rising edge of CAB.
The data in the A storage flip-flops are displayed
on the B bus.
The data on the A bus are stored into the A
storage flip-flops on the rising edge of CAB, and
the stored data propagate directly onto the B bus.
The data in the A storage flip-flops are displayed
on the B bus, and the data in the B storage
flip-flops are displayed onthe A.
X: Don’t care
Qn: The data stored into the internal flip-flops by most recent low to high transition of the clock inputs.
Z: High impedance
Note:
The clocks are not internally gated with either output enable or select inputs. Therefore, data on the A
and/or B busses may be clocked into the storage flip-flops at any time.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 2: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be
applied until 300 mW.
