Translates between GTLP logic levels (B ports) and LVTTL/TTL
logic levels (A ports)
Edge rate control circuitry on the Bn outputs rising/falling edges to
minimize system noise in a multipoint backplane environment
5 V I/O tolerant on the LVTTL side
No bus current loading when LVTTL output is tied to 5 V bus
3-State buffers
Output capability: +64 mA/-32 mA on the LVTTL side; +40 mA on
the GTLP side
LVTTL input levels on control pins
Power-up reset
Power-up 3-State
Positive edge triggered clock inputs
Latch-up protection exceeds 500 mA per JESD78
ESD protection exceeds 2000 V HBM per JESD22-A114,

CDM per JESD22-C101
DESCRIPTION
The GTLPH16612 is a high-performance BiCMOS product designed
for V
CC
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 V
CC
or 3.3 V BIAS V
CC
.
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.
