74LVT16646A
3.3 V 16-bit bus transceiver; 3-state
The 74LVT16646A is a high-performance BiCMOS product designed for VCC operation at 3.3 V. This device is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an output enable (OE) input for easy cascading and a direction (DIR) input for direction control.
Data on bus A or bus B is clocked into the registers on the LOW-to-HIGH transition of the appropriate clock (CPAB or CPBA). The select control (SAB and SBA) inputs can multiplex stored and real-time (transparent mode data).
Features and benefits
- 16-bit universal bus interface
- 3-state buffers
- Output capability: from +64 mA to -32 mA
- TTL input and output switching levels
- Input and output interface capability to systems at 5 V supply
- Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs
- Live insertion and extraction permitted
- No bus-current loading when output is tied to 5 V bus
- Power-up reset
- Power-up 3-state
- Latch-up protection exceeds 500 mA per JESD78
- ESD protection:
- MIL STD 883 Method 3 015: exceeds 2000 V
- Machine model: exceeds 200 V
