GTLPH16612: 50 Pin electronic Component

The GTLPH16612 is a high-performance BiCMOS electronic component designed for VCC operation at 3.3V with I/O compatibility up to 5 V. The GTLPH16612 is unique in that pin 50 is a no connect and this device can be used as a replacement device in sockets where pin 50 is 3.3/5 V VCC or 3.3 V BIAS VCC.

This device is an 18-bit universal transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. Data flow in each direction is controlled by output enable (OEAB and OEBA), latch enable (LEAB and LEBA), and clock (CPAB and CPBA) inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is High. When LEAB is Low, the A data is latched if CPAB is held at a High or Low logic level. If LEAB is Low, the A-bus data is stored in the latch/flip-flop on the Low-to-High transition of CPAB. When OEAB is Low, the outputs are active. When OEAB is High, the outputs are in the high-impedance state. The clocks can be controlled with the clock-enable inputs (CEBA/CEAB). Data flow for B-to-A is similar to that of A-to-B but uses OEBA, LEBA and CPBA.
