FEATURES
Two 8-bit registered transceivers 5V I/O Compatible 3-State buffers Output capability: +64mA/–32mA TTL input and output switching levels Input and output interface capability to systems at 5V supply Bus hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
DESCRIPTION
The 74ALVT16952 is a high-performance BiCMOS product designed for VCC operation at 2.5V or 3.3V with I/O compatibility up to 5V. The 74ALVT16952 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. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
Live insertion/extraction permitted Power-up 3-State Power-up reset No bus current loading when output is tied to 5V bus Latch-up protection e...
