I
Read/write. High-level input selects read mode and a low-level input selects write
mode.
RDX, RDY
16, 17
O
Read data. Differential read-data output
VCC
10
I
Supply voltage
WCS

I
Write-current set. Used to set the magnitude of the write-current bias. Can be wire
ORed when more than one device is used.
WDY, WDX
12, 13
I
Write data. Pseudo ECL, differential write-data input
WUS/SE
11
I/O
Write unsafe. Indicates write current is zero, mode is read, WDX/WDY frequency is
low, device is not selected, head is shorted or open, or low VCC.
Servo enable. When SE = VCC + 1.9 V, the servo-write head is turned on.
