TC7MA2573FK 2001-10-23 1 toshiba cmos digital integrated circuit silicon monolithic TC7MA2573FK low-voltage octal d-type latch with 3.6 v tolerant inputs and outputs the TC7MA2573FK is a high performance cmos octal d-type latch. designed for use in 1.8 v, 2.5 v or 3.3 v systems, it achieves high speed operation while maintaining the cmos low power dissipation. it is also designed with over voltage tolerant inputs and outputs up to 3.6 v. this 8 bit d-type latch is controlled by a latch enable input (le) and an output enable input (oe). when the oe input is high, the eight outputs are in a high impedance state. the 26 ? series resistor helps reducing output overshoot and undershoot without external resistor. all inputs are equipped with protection circuits against static discharge. features 26 ? series resistors on outputs. low voltage operation: v cc = 1.8~3.6 v high speed operation: t pd = 5.1 ns (max) (v cc = 3.0~3.6 v) t pd = 6.1 ns (max) (v cc = 2.3~2.7 v) t pd = 9.8 ns (max) (v cc = 1.8 v) 3.6 v tolerant inputs and outputs. output current: i oh /i ol = 12 ma (min) (v cc = 3.0 v) i oh /i ol = 8 ma (min) (v cc = 2.3 v) i oh /i ol = 4 ma (min) (v cc = 1.8 v) latch-up performance: 300 ma esd performance: machine model > 200 v human body model > 2000 v package: vssop (us20) power down protection is provided on all inputs and outputs. supports live insertion/withdrawal ( * ) * : to ensure the high-impedance state during power up or power down, oe should be tied to v cc through a pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. weight: 0.03 g (typ.)
