INTEGRATED CIRCUITS 74LVT16543A 3.3V LVT 16-bit registered transceiver (3-State) Product specification Supersedes data of 19 IC23 Data Handbook 1998 Feb 19 Philips Semiconductors Product specification 3.3V 16-bit registered transceiver (3-State) FEATURES 74LVT16543A DESCRIPTION • 16-bit universal bus interface • 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 The 74LVT16543A is a high-performance BiCMOS product designed for VCC operation at 3.3V. The device can be used as two 8-bit transceivers or one 16-bit transceiver. The 74LVT16543A contains two sets of eight D-type latches, with separate control pins for each set. Using data flow from A to B as an example, when the A-to-B Enable (nEAB) input and the A-to-B Latch Enable (nLEAB) input are Low, the A-to-B path is transparent. resistors to hold unused inputs • 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 exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000V per MIL STD 883 Method 3015 A subsequent Low-to-High transition of the nLEAB signal puts the A data into the latches where it is stored and the B outputs no longer change with the A inputs. With nEAB and nOEAB both Low, the 3-State B output buffers are active and display the data present at the outputs of the A latches. Control of data flow from B to A is similar, but using the nEBA, nLEBA, and nOEBA inputs. and 200V per Machine Model Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
