PIN CONNECTIONS (top view)
M74HC651/652 are high speed CMOS OCTAL
BUS TRANSCEIVERS AND REGISTERS (3-
STATE), fabricated in silicon gate C2MOS technol-
ogy. They have the same high speed performance
of LSTTL combined with true CMOS low power con-
sumption. These devices consist of bus transceiver
circuits, D-type flip-flops, and control circuitry ar-
ranged for multiplexed transmission of data directly
from the input bus or from the internal storage reg-
isters. Enable GAB and GBA are provided to control
the transceiver functions.
Select AB and Select BA control pins are provided
to select whether real-time or stored data is trans-
fered. A low input level selects real-time data, and
a high selects stored data.
Data on the A or B bus, or both, can be stored in the
internal D flip-flops by low-to-high transitions at the
appropriate clock pins (CLOCK AB or CLOCK BA)
regardless of the select or enable control pins. When
select AB and select BA are in the real-time transfer
mode, it is also possible to store data without using
the internal D-type flip-flops by simultaneously en-
abling GAB and GBA. In this configuration each out-
put reinforces its input. Thus, when all other data
sources to the two sets of bus lines are at high im-
pedance, each set of bus lines will remain at its last
state. All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/8 (per Channel)
