Frequently Asked Questions
What is the bit-width and direction mode of the 74LVCHR16245AGRG4?
The 74LVCHR16245AGRG4 is a 16-bit bidirectional bus transceiver. A single DIR pin controls the direction of all 16 bits simultaneously, while an active-LOW OE pin enables or disables all outputs, providing simple and efficient control for half-duplex data bus operations.
Can the 74LVCHR16245AGRG4 translate between 3.3V and 5V logic?
Yes, the 74LVCHR16245AGRG4 is designed for dual-supply level translation. Its inputs are 5V-tolerant while operating from a 3.3V supply, allowing direct interface between 3.3V LVC-family processors and legacy 5V TTL systems without external level-shifting circuitry.
What is the output current drive capability of the 74LVCHR16245AGRG4?
The 74LVCHR16245AGRG4 provides a maximum output sink current of 12mA (I_OL), which enables it to drive moderate capacitance bus lines reliably while maintaining valid TTL output logic levels, suitable for typical PCB backplane interconnect applications.
What package does the 74LVCHR16245AGRG4 use?
The 74LVCHR16245AGRG4 is housed in a 48-pin TSSOP (Thin Shrink Small Outline Package), which offers a compact footprint with 0.5mm pin pitch, suitable for high-density surface-mount PCB designs in embedded computing and telecommunications equipment.
