无差错POWER UP 19位IEEE STD 1284转换收发器 19-BIT IEEE STD 1284 TRANSLATION TRANSCEIVER WITH ERROR-FREE POWER UP
The SN74LVCZ161284A is designed for 3-V to 3.6-V VCC operation. This device provides asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.
This device has eight bidirectional bits; data can flow in the A-to-B direction when the direction-control input DIR is high, and in the B-to-A direction when DIR is low. This device also has five drivers that drive the cable side, and four receivers. The SN74LVCZ161284A has one receiver dedicated to the HOST LOGIC line and a driver to drive the PERI LOGIC line.
The output drive mode is determined by the high-drive HD control pin. When HD is high, the outputs are in a totem-pole configuration, and in an open-drain configuration when HD is low. This meets the drive requirements as specified in the IEEE Std 1284-I level-1 type and IEEE Std 1284-II level-2 type parallel peripheral-interface specifications. Except for HOST LOGIC IN and peripheral logic out PERI LOGIC OUT, all cable-side pins have a 1.4-k integrated pullup resistor. The pullup resistor is switched off if the associated output driver is in the low state or if the output voltage is above VCC CABLE. If VCC CABLE is off, PERI LOGIC OUT is set to low.
The device has two supply voltages. VCC is designed for 3-V to 3.6-V operation. VCC CABLE supplies the inputs and output buffers of the cable side only and is designed for 3-V to 3.6-V and for 4.7-V to 5.5-V operation. Even when VCC CABLE is 3 V to 3.6 V, the cable-side I/O pins are 5-V tolerant.
The Power-On Reset POR ensures that the Y outputs Y9Y13 stay in the high state after power on until an associated input A9A13 goes high. When an associated input goes high, all Y outputs are activated, and noninverting signals of the associated inputs are driven through Y outputs. This special feature prevents printer system errors caused by deasserting the BUSY signal in the cable at power on.
