GTL16612
Datasheet
General description
The GTL16612 is a high-performance BiCMOS product designed for VCC operation at 3.3 V with I/O compatibility up to 5 V.
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.
Features
- 18-bit bidirectional bus interface
- Translates between GTL/GTL+ logic levels (B ports) and LVTTL/TTL logic levels (A ports)
- 5 V I/O tolerant on the LVTTL/TTL side (A ports)
- No bus current loading when LVTTL/TTL output is tied to 5 V bus
- 3-State buffers
- Output capability: +64 mA/-32 mA on the LVTTL/TTL side (A ports); +40 mA on the GTL/GTL+ side (B ports)
- TTL 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, 200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101
