LowVoltage CMOS Octal
Transceiver/Registered
Transceiver
With 5 VTolerant Inputs and Outputs
(3State, NonInverting)
The MC74LCX646 is a high performance, noninverting octal
transceiver/registered transceiver operating from a 2.3 to 3.6 V supply.
High impedance TTL compatible inputs significantly reduce current
loading to input drivers while TTL compatible outputs offer improved
switching noise performance. A VI specification of 5.5 V allows
MC74LCX646 inputs to be safely driven from 5 V devices. The
MC74LCX646 is suitable for memory address driving and all TTL
level bus oriented transceiver applications.
Data on the A or B bus will be clocked into the registers as the
appropriate clock pin goes from a LOWtoHIGH logic level. Output
Enable (OE) and DIR pins are provided to control the transceiver
outputs. In the transceiver mode, data present at the high impedance
port may be stored in either the A or the B register or in both. The
select controls (SBA, SAB) can multiplex stored and realtime
(transparent mode) data. The direction control (DIR) determines
which bus will receive data when the enable OE is active LOW. In the
isolation mode (OE HIGH), A data may be stored in the B register or B
data may be stored in the A register. Only one of the two buses, A or B,
may be driven at one time.
