What are the key features of 74LVCE161284VRE4?
- 19-bit IEEE-1284 compliant bidirectional bus transceiver enabling full parallel port translation between host and peripheral
- 14-bit driver configuration with 50 µA maximum high-level input current for low-power interface operation
- 48-pin PDSO-G48 Small Outline package with e4 RoHS lead-free construction for green supply chain compliance
What is 74LVCE161284VRE4 used for?
74LVCE161284VRE4 is designed for parallel printer port interface circuits that must comply with IEEE-1284 protocol for bidirectional data transfer between a host PC and a peripheral device. It is used in legacy parallel-port to USB bridge adapters, industrial printers, and multi-function devices that require reliable 8-bit to 19-bit bus translation at standard parallel interface voltages. The low 50 µA input current draw also makes it suitable for battery-assisted handheld printers and low-power print servers.

Frequently Asked Questions
How many driver bits does 74LVCE161284VRE4 provide, and which IEEE interface standard does it implement?
74LVCE161284VRE4 implements the IEEE-1284 parallel interface standard and provides 14 driver bits plus additional control lines for a total 19-bit bus. This 14-bit driver width covers the 8 data bits and 6 status/control lines required for full IEEE-1284 compatibility in bidirectional Nibble, Byte, and ECP modes.
For a legacy parallel-port interface design, what is the maximum high-level input current of 74LVCE161284VRE4 and why does it matter?
The maximum high-level input current is 50 µA (0.00005 A). This low 50 µA input leakage allows many 74LVCE161284VRE4 devices to share a common bus backplane without exceeding the drive capability of a standard host parallel port, which is typically rated for only a few milliamps of bus leakage across all connected loads.
In what package does 74LVCE161284VRE4 come and how does pin count affect PCB layout for parallel port adapters?
74LVCE161284VRE4 is housed in a 48-pin PDSO-G48 Small Outline package with 0.635 mm pitch. A 48-pin SOIC occupies roughly 30 mm x 8 mm of PCB area, which is sufficient to route all 19 IEEE-1284 bus lines with short trace lengths, minimizing signal crosstalk at the 1 MHz to 4 MHz data rates used in ECP parallel port transfers.
