Fast CMOS 3.3V 16-Bit 1
Transparent Latch
Product Features
• Compatible with LCX™ and LVT™ families of products
Product Description
2
Pericom Semiconductor’s PI74LPT series of logic circuits are pro-
• Supports 5V Tolerant Mixed Signal Mode Operation
duced in the Company’s advanced 0.6 micron CMOS technology,
– Input can be 3V or 5V
achieving industry leading speed grades.
– Output can be 3V or connected to 5V bus
• Advanced Low Power CMOS Operation
3 The PI74LPT16373 is a 16-bit transparent latch designed with
3-state outputs and are intended for bus oriented applications. The
• Excellent output drive capability:
Output Enable and Latch Enable controls are organized to operate
Balanced drives (24 mA sink and source)
as two 8-bit latches or one 16-bit latch. When Latch Enable (LE) is
• Pin compatible with industry standard double-density
pinouts
• Low ground bounce outputs
• Hysteresis on all inputs
• Industrial operating temperature range: –40°C to +85°C
4 HIGH, the flip-flops appear transparent to the data. The data that
meets the set-up time when LE is LOW is latched. When OE is
HIGH, the bus output is in the high impedance state.
5 The PI74LPT16373 can be driven from either 3.3V or 5.0V devices
allowing this device to be used as a translator in a mixed
3.3/5.0V system.
• Multiple center pins and distributed Vcc/GND pins
minimize switching noise
• Packages available:
6
– 48-pin 240 mil wide thin plastic TSSOP (A)
– 48-pin 300 mil wide plastic SSOP (V)
