FEATURES
• Complies with JEDEC standard no. 8-1A
DESCRIPTION
The 74ALVCH16952 consists of two sections, each containing a
dual octal non-inverting registered transceiver. Two 8-bit back to
back registers store data flowing in both directions between two
bi-directional busses. Data applied to the inputs is entered and
• CMOS low power consumption
TM
• MULTIBYTE flow-through pin-out architecture
stored on the rising edge of the clock (CP , where X is AB or BA)
XX
provided that the clock enable (CE ) is LOW. The data is then
present at the 3-State output buffers, but is only accessible when the
• Low inductance, multiple center power and ground pins for
XX
minimum noise and ground bounce
output enable input (OE ) is LOW. Data flow from A inputs to B
XX
• Direct interface with TTL levels
outputs is the same as for B inputs to A outputs.
• Output drive capability 50Ω transmission lines @ 85°C
