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.
• 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
w These devices are available in Pb−free package(s). Specifications herein
apply to both standard and Pb−free devices. Please see our website at
www.onsemi.com for specific Pb−free orderable part numbers, or
