MC74AC652, MC74ACT652
Octal Transceiver/Register
with 3-State Outputs
(Non-Inverting)
The MC74AC/ACT652 consists of registered bus transceiver
circuits, with outputs, D−type flip−flops and control circuitry
providing multiplexed transmission of data directly from the input bus
or from the internal storage registers. Data on the A or B bus will be
loaded into the respective registers on the LOW−to−HIGH transition
of the appropriate clock pin (CAB or CBA). The four fundamental
data handling functions available are illustrated in Figures 1 to 4.
Features
• Independent Registers for A and B Buses
• Multiplexed Real−Time and Stored Data Transfers
• Choice of True and Inverting Data Paths
• 3−State Outputs
• 300 mil Slim Dual−in−Line Package
• Outputs Source/Sink 24 mA
• ′ACT652 Has TTL Compatible Inputs
• These are Pb−Free Devices
