Description : 74F2952 REGISTERED TRANSCEIVER, non-inverting (3-STATE) 74F2953 REGISTERED TRANSCEIVER, inverting (3-STATE) View

DESCRIPTION
The 74F2952 and 74F2953 are 8-bit REGISTERED TRANSCEIVERs. Two 8-bit back-to-back registers store data flowing in both directions between two bi-directional buses. Data applied to the inputs is entered and stored on the rising edge of the Clock (CPXX) provided that the Clock Enable (CEXX) is Low. The data is then present at the 3-STATE output buffers, but is only accessible when the Output Enable (OEXX) is Low. Data flow from ‘A’ inputs to ‘B’ OUTPUTS is the same as for ‘B’ inputs to ‘A’ OUTPUTS.

FEATURES
• 8-bit REGISTERED TRANSCEIVERs
• Two 8-bit, back-to-back registers store data moving in both directions between two bidirectional buses
• Separate Clock, Clock Enable and 3-STATE Enable provided for each register
• 74F2952 non-inverting

DESCRIPTION
The 74ABT16952 high-performance BiCMOS device combines low static and dynamic power dissipation WITH high speed and high output drive.
The 74ABT16952 is a dual octal REGISTERED TRANSCEIVER. Two 8-bit registers store data flowing in both directions between two bidirectional buses. Data applied to the inputs is entered and stored on the rising edge of the Clock (nCPXX) provided that the Clock Enable (nCEXX) is Low. The data is then present at the 3-STATE output buffers, but is only accessible when the Output Enable (nOEXX) is Low. Data flow from A inputs to B OUTPUTS is the same as for B inputs to A OUTPUTS.
Two options are available, 74ABT16952 which does not have the bus-hold feature and 74ABTH16952 which incorporates the bus-hold feature.
