Fairchild expands TinyLogic(tm)
portfolio with the addition of
four new dual 3-state buffers
Smallest available leaded package for dual logic functions
Fairchild Semiconductor International's Interface and Logic
Group continues to provide designers with innovative Logic solutions
in the smallest leaded packages available. The addition of four
new CMOS 3-state dual buffers in the US8 package have particular
value in portable battery powered devices such as cell phones
and mobile computers.
By assuming a high impedance output when the downstream function
i.e. ASIC is disabled, current drive for a logic high or low
is avoided, and battery power is conserved. The new NC7WZ125K8
and NC7WZ126K8 functions are dual non-inverting buffers with
an active high and an active low, respectively, to enable the
high impedance state. The NC7WZ240K8 is a dual inverting buffer
with active low enable for the high Z state, while the NC7WZ241K8
dual buffers version combines independent 125 and 126 functions
within the same package.
These ultra high-speed devices are fabricated with advanced
CMOS technology to achieve superior performance with high output
drive while maintaining low static power dissipation over a
broad VCC operating range. Specified to operate over the 1.65V
to 5.5V VCC operating range, the inputs and outputs are high
impedance when VCC is 0V. Inputs tolerate voltages up to 5.5V
independent of VCC operating range, while outputs tolerate voltages
above VCC when in the 3-STATE condition. In addition these devices
have the high-speed characteristics of TinyLogic UHS family,
TPLH and TPLL speed is 1-2ns typ at 3.3 V, 5.7ns max, making
these ideal for use in high-speed computing devices. Skew between
buffer outputs is also specified at 1ns maximum.
The US8 package measures just 2.0 mm x 3.1 mm, including the
leads, with a maximum height of 0.7 mm. Compared to 14 lead
TSSOP package devices, these dual buffers in US8 packages require
1/5 of the customer's board mounting area making them ideal
for use in compact low profile systems such as laptops, cell
phones, digital cameras, PDAs and PCMCIA cards.
The new logic functions are priced at US$0.34 in 10,000-piece
quantities. Samples and production quantities are available.
